On 1 June 2021, EarthQuaker Devices published a blog post with the title Dead Pedal Office and quietly buried the only product family it had ever built. The Disaster Transport SR went to the Legacy page. Its smaller relatives — the original Disaster Transport and the four-knob Disaster Transport Jr. — were already there waiting for it.
“The Disaster Transport series is the only series we’ve done,” Jamie Stillman told the company’s own writer, Malcolm X Abram. “There’s been a Disaster Transport of some sort or another in the line since EarthQuaker started.” And then there wasn’t.
The Jr. is the one people forget. It has no modulation, no expression jack, no reverb, no tap tempo, no presets, no second footswitch, and it is roughly the size of a wallet. What it has is a tone control that behaves like nothing else in the delay world, a mix knob that will boost your repeats to four times the level of your dry signal, and a set of design decisions so contrarian that EarthQuaker’s own manual describes the pedal as “an anti-modern delay.”
Dan Auerbach kept one in his backup rig. Two members of King Gizzard and The Lizard Wizard have had one on their boards. Michelle Zauner of Japanese Breakfast is listed as an EarthQuaker artist. And on the used market in 2026 the thing costs about a hundred dollars, which is the single most interesting fact in this entire article.
This is a feature, not a review. We are not scoring it. What follows is where the Disaster Transport Jr. came from, exactly what its four knobs do and why the Tone control is the one that matters, which players are genuinely documented using it and which attributions fall apart under a second look, eight settings worth stealing, and an honest account of who should walk past it.
Akron’s Founding Circuit
The full EarthQuaker origin story — Jamie Stillman, a former Black Keys road manager, hand-building fuzz boxes in an Akron, Ohio basement and turning that into one of the most consequential American pedal companies of the century — is told in our piece on the EarthQuaker Devices Hoof, and we will not repeat it here. What matters for the Jr. is that the Disaster Transport is not just an early EarthQuaker pedal. It is the early EarthQuaker pedal, in the sense that it is the only design the company ever grew into a family.
The chronology, taken directly from EarthQuaker’s own 2021 obituary post:
- 2007 — the original Disaster Transport, a modulated delay built around a PT2399-style delay line with a ramp-wave LFO. This is the company’s foundational product.
- 2010 — a revised version of the original, and, in the same year, the Disaster Transport Jr., described in EarthQuaker’s own words as “the cute little offspring.”
- 2013 — the Disaster Transport SR, the first genuinely large-format EarthQuaker pedal: dual delays, reverb, modulation, series/parallel bleed control, and expression control over repeats or bleed.
- 1 June 2021 — the SR is discontinued and the entire family goes to the Legacy page.
- 2 June 2023 — the Disaster Transport Legacy Reissue arrives, limited to 3,500 units worldwide at $219 / £235, plus a 500-unit artwork edition by Pieter “Parra” Janssen sold through Reverb at $249 / £210.
Stillman’s explanation for killing the SR is the most quotable thing any pedal executive has said about discontinuation. “The sales are low, it’s an extremely difficult pedal for us to build and it takes up a lot of production time,” he said, flatly. “Even though there is nothing else in our line that does exactly what the Disaster Transport SR does, it has run its course and it’s time for it to be discontinued.” He added that he had been advocating for dropping it for years, and that the smaller-footprint delays — the Dispatch Master, the Avalanche Run, the Space Spiral — had simply won.
A note on dates, because the sources disagree
EarthQuaker’s own blog post puts the Jr. in 2010, and the Jr.’s operation manual carries a © 2010 EarthQuaker Devices LLC line, which is about as close to primary documentation as this kind of question gets. Equipboard’s spec table lists the production years as “2011 – 2015.” We are going with 2010 as the launch year on the strength of the manual, while acknowledging that 2011 may well be when the pedal reached wide retail distribution and that 2015-ish is a plausible end of production. If you see 2011 quoted elsewhere, this is why.
Specifications
What “Analogue-Voiced Digital Delay” Actually Means
This phrase gets thrown around loosely enough that it is worth unpacking, because in the Jr.’s case it is precise rather than promotional.
The delay line itself is digital — a PT2399-family chip, the same inexpensive, slightly noisy, gloriously characterful part that sits at the heart of an enormous number of boutique delays. The dry signal never touches it. Your straight guitar tone passes through analogue circuitry from input to output; only the repeats are digitised. That is what “all analog dry signal path” means, and it is the reason the Jr. does not thin out or glassify your core tone the way some early digital delays did.
Here is where a widely-circulated description gets it wrong. Equipboard’s product page claims the Jr. has a “purely analog signal path” that ensures “your tone remains uncolored and true.” That is a garbled restatement of EarthQuaker’s actual wording. The Jr. is not an analogue delay. It has no bucket-brigade chips. If you are cross-shopping it against a genuine BBD unit like the MXR Carbon Copy, the Boss DM-2W or the Maxon AD999, you should know that you are comparing an analogue circuit to a digital one that has been deliberately voiced to behave like tape. That is not a criticism of the Jr. — it is arguably why the Jr. sounds the way it does — but it is a material fact and the source most people will land on gets it backwards.
The design thesis, in EarthQuaker’s own words
The manual is unusually explicit about what problem the pedal was built to solve, and the passage is worth reading in full because it explains the entire circuit:
“Most delay pedals are heavily filtered at the output to remove the clock noise and other unwanted hash that is common from extending the range of the delay time beyond the limit of the circuitry. This usually leaves the delay sounding dark, muddy and disappear when hitting it with dirt. The Disaster Transport has done away with a lot of the heavy filtering and replaced it with a tone control which allows the user to choose their desired sound and results in more natural tape-like repeats.”
Read that again, because it is the thesis of the pedal. Most cheap digital delays sound dark on purpose, to hide artefacts. EarthQuaker’s move was to take the filter out and hand it to you as a knob. You get the brightness back if you want it. You get the noise back too. That is the deal.
The consequence is the thing owners actually notice: the Jr. survives being hit with distortion. A dark, heavily-filtered delay disappears underneath a fuzz pedal. A Jr. with the Tone knob past noon does not. Run it after a Big Muff Pi or the Hoof and the repeats stay legible instead of turning into brown mush.
The Four Controls, Decoded
Mix — this is a gain control, not a blend
This is the single most misunderstood knob on the pedal and the one that separates people who love the Jr. from people who bounce off it. Mix does not crossfade between dry and wet. It sets the output level of the delay line only, and EarthQuaker’s manual tells you to “treat it as a gain control / master volume for the delay line.”
Unity is around noon. Everything above noon boosts the repeats louder than your dry signal — up to roughly four times the original signal level at maximum. This is a genuinely unusual amount of headroom for a delay’s wet path and it is the source of the Jr.’s most dramatic sounds: repeats that swell over the top of the note that spawned them, feedback that builds rather than decays, a slapback that is louder than the pick attack.
EarthQuaker also warn you, honestly, that “like any pedal with a lot of gain, a hint of noise and distortion at max setting is completely normal.” That is not a defect report, it is a design statement. If you want a silent, transparent, studio-grade delay, the Jr. is not it and never claimed to be.
Tone — the noise filter you get to aim
Darkest fully counter-clockwise, brightening as you turn clockwise. Its official function is voicing; its practical function is noise management. EarthQuaker’s rule of thumb from the manual: at longer delay times, keep Tone between fully counter-clockwise and noon. That removes “all the common noise from hyper-extending the circuit.”
In other words, the Tone control is inversely coupled to the Time control in practice. Long delays want a dark Tone. Short delays can take all the brightness you want. Nobody puts this on the box, but it is how the pedal is actually operated.
Time — 30 ms to 625 ms
Roughly 30 ms fully counter-clockwise to roughly 625 ms fully clockwise. That upper limit is modest by 2026 standards — the Strymon TimeLine will give you multiple seconds — but it is entirely in line with the Jr.’s tape-echo brief. A Roland Space Echo does not do two-second delays either. 625 ms is a dotted eighth at about 96 bpm, or a straight quarter at 96 bpm, which puts it comfortably inside the tempo range of most rock.
Worth noting: like all PT2399-based designs, the exact maximum varies unit to unit. EarthQuaker acknowledge this openly on the Legacy Reissue’s page, explaining that “the pt2399 is an older and unique IC, which can have variable tolerances. As a result, some units may produce longer delay times compared to others.” Two Disaster Transport Jr.s are not guaranteed to be identical at the extremes. Treat “625 ms” as a nominal figure.
Repeats — with a full clock map
EarthQuaker did something in the Jr.’s manual that almost no manufacturer bothers with: they gave you positional landmarks rather than a vague sweep description.
- Fully counter-clockwise — one single repeat
- 9 o’clock — subtle repeats
- Noon — strong, naturally decaying repeats
- 2 o’clock — near-infinite repeats
- Fully clockwise — full self-oscillation
That map is the most useful paragraph in the manual and we have built most of the tone recipes below around it.
What is not here
No modulation. No tap tempo. No presets. No expression jack. No trails — the bypass is genuine mechanical true bypass, so switching off cuts the repeats dead. No stereo. No MIDI. One footswitch, four knobs, one job.
Famous Players: What Holds Up And What Doesn’t
The spreadsheet entry that sent us here carried no artist claims at all, which was honest of it. We ran the check anyway, and the results are more interesting than expected for a small discontinued pedal.
Tier one: independently documented
Dan Auerbach (The Black Keys) — the strongest attribution, and the one with a caveat that makes it better rather than worse. Premier Guitar’s 2014 Rig Rundown lists the Disaster Transport Jr. among the pedals on Auerbach’s setup, alongside an EarthQuaker Terminal Fuzz, a Hoof and a Tone Job. The detail worth knowing: it appears in the description of his backup rig, the duplicate board built to cover a failure on the main one. That is not a downgrade. Touring musicians do not spend money duplicating pedals they are ambivalent about, and the presence of four EarthQuaker boxes on a Black Keys spare board in 2014 says something specific about how deep the Akron connection ran. Equipboard additionally logs the Jr. against El Camino (2011) and Turn Blue (2014); those are community-submitted album credits rather than documented studio evidence, and we would not build an argument on them, though the timeline at least works.
Michelle Zauner / Japanese Breakfast — listed as an artist on EarthQuaker’s own website. Manufacturer-published artist rosters are the one form of second-hand evidence we treat as reliable, because a company has a legal and reputational interest in not inventing endorsements.
Miguel Briseño — EarthQuaker’s own artist page states the Disaster Transport Jr. is part of his current pedalboard. Same reasoning as above. See the correction note below regarding which band he actually plays in.
Tim Showalter / Strand of Oaks — talks about his pedalboard on camera and names both the Disaster Transport Junior and Senior. First-person, on video. Equipboard also logs the Jr. on HEAL (2014).
Tier two: photographic and interview evidence
Stu Mackenzie and Cook Craig (King Gizzard and The Lizard Wizard) — two separate board photographs, Mackenzie’s from a November 2016 AudioTechnology interview, Craig’s from a circulated board shot. Two members of the same band independently owning the same small discontinued delay is a meaningful data point, and the Jr.’s character — bright, gritty, capable of runaway self-oscillation, cheap enough to abuse — fits King Gizzard’s whole methodology better than almost any premium delay would.
Devin Yüceil (Delta Sleep) — pedalboard photograph from an Atlanta show, originally posted to r/guitarpedals.
Michael Gibbons (Bardo Pond) — photographed using one at a show dated 18 April 2015. Bardo Pond is arguably the most on-brief user on this list; a band whose entire catalogue is built from slow, heavy, saturated drone is exactly the audience for a delay that stays audible under fuzz.
Jonathan Meiburg — visible on his pedalboard in a photograph of Shearwater’s rigs.
yuuho kitazawa (the peggies) — a posted board photo, described as last in her chain.
Matthew Stevens — mentions using the Jr. in a Strymon interview.
Dallas Green — the most interesting entry, because the evidence is about a pedal the Jr. was replaced by. The Nice Rack Canada documentation of his rig rebuild shows the Jr. in the “before” photo, and notes that in the new build “the Carbon Copy had been used exclusively on the Acoustic Guitar and set to emulate the Disaster Transport Jr.” So: a documented former user whose tech’s brief on the replacement pedal was to imitate this one. That is a backhanded compliment, but it is a compliment, and it tells you the Jr. has a recognisable enough voice to be worth copying.
Three attributions we are correcting
Equipboard’s band fields disagreed with its own captions three separate times on this page, which is a rate high enough to be worth flagging for anyone using it as a source.
- Miguel Briseño is filed under Lord Huron. He is the bassist and keyboardist of Black Pumas. The EarthQuaker artist-page evidence stands; the band attribution does not.
- Jonathan Meiburg is filed under Okkervil River, while the caption underneath describes a photograph of Shearwater‘s pedalboards. Meiburg played in Okkervil River early on, but Shearwater is his band and Shearwater is what the photo shows.
- Dallas Green is filed under Alexisonfire, while the caption is about an acoustic-guitar signal path — which is City and Colour territory, not Alexisonfire’s.
None of these break the underlying gear claim. All three would have been reproduced verbatim by anyone who trusted the field instead of reading the caption.
Where the SR gets confused with the Jr.
MusicRadar’s coverage of the 2023 reissue names Dan Auerbach, Lee Kiernan of Idles, Gina Gleason of Baroness and Misha Mansoor of Periphery as users — of the Disaster Transport SR, the big one, not the Jr. Matt Sorum shows up on Equipboard with an SR as well. If you go looking for Disaster Transport artist lists you will find the SR’s roster attached to the Jr. constantly. They are different pedals with different feature sets and, in Mansoor’s case in particular, an entirely different application.
The other name in the family’s story belongs to the SR too, and it is the best testimonial EarthQuaker ever printed. Jimmy Carbonetti of Caveman told the company’s own writer that he first met the original Disaster Transport during a gear emergency at a CMJ show: “I had to run to Ludlow Guitars to get a delay and I tried like 10 pedals, and the Disaster Transport won. It was like my Space Echo. I fell in love and I never turned it off from the day I got it.” He later replaced a Space Echo and a Third Hand volume rig with an SR and said it had been “Caveman’s sound” ever since. The Jr. is not that pedal, but it is that pedal’s delay line with the fat trimmed off.
Eight Settings Worth Stealing
EarthQuaker published no suggested settings for the Jr., which is consistent with their approach across the range — the Afterneath and the Rainbow Machine manuals are equally silent. The following are reverse-engineered from the manual’s own Repeats clock map, its Tone guidance and the documented behaviour of the Mix control. Knob positions are clock references.
1. Rockabilly slapback
Time 8 o’clock (roughly 90–120 ms) · Repeats fully counter-clockwise (single repeat) · Mix 1 o’clock · Tone 2 o’clock
One repeat, bright, slightly louder than the dry note. Short time settings are where you can safely run the Tone control hot, and the Jr.’s wet-path gain is what gives this a snap that most delays cannot manage. The Brian Setzer and Sun Studio end of the vocabulary.
2. The dirty lead delay
Time 11 o’clock · Repeats noon · Mix 11 o’clock · Tone 1 o’clock
The setting the pedal was designed for. Put it after a fuzz or a Tube Screamer, keep the Tone up, and the repeats remain articulate under gain instead of smearing. This is the direct answer to the “dark, muddy, disappears when hit with dirt” complaint in EarthQuaker’s manual.
3. Tape echo emulation
Time 2 o’clock · Repeats 1 o’clock · Mix 10 o’clock · Tone 10 o’clock
Long time, dark Tone per EarthQuaker’s own rule of thumb, repeats piling up but still decaying. The PT2399’s own artefacts do the rest of the work. Compare with a Boss RE-2 Space Echo and you will hear what the Jr. gives up in realism and what it gains in bite.
4. Ambient wash
Time fully clockwise · Repeats 2 o’clock · Mix noon · Tone 9 o’clock
Near-infinite repeats at 625 ms with the Tone rolled well back. Play sparse, let it build. Add a reverb after it — the EHX Oceans 11 or an Afterneath — and the Jr. becomes the rhythm engine underneath the pad rather than the pad itself.
5. Runaway oscillation
Time anywhere · Repeats fully clockwise · Mix 3 o’clock · Tone noon
Full self-oscillation with the wet gain well above unity. Ride the Time knob while it screams and you get pitch dives and rising sirens. This is where the Jr.’s absent noise filtering becomes the whole point — an over-filtered delay oscillates into a dull hum, this one oscillates into something with teeth. Mind your amp and your ears.
6. Doubling, not delaying
Time fully counter-clockwise (about 30 ms) · Repeats fully counter-clockwise · Mix 10 o’clock · Tone noon
At 30 ms the repeat stops being heard as an echo and starts being heard as thickness. Underneath the dry signal it functions as a crude double-track. This is the Jr.’s quietest and most useful “always on” setting, and it is the one most people never find.
7. Louder-than-life swell
Time 1 o’clock · Repeats 11 o’clock · Mix fully clockwise · Tone 11 o’clock
The showcase for the four-times-unity mix gain. Play one note and the echo arrives louder than the note. Deeply unnatural, extremely effective on a sparse arrangement, and impossible on any delay with a conventional dry/wet blend.
8. Bass delay that doesn’t disappear
Time 10 o’clock · Repeats 9 o’clock · Mix 9 o’clock · Tone 2 o’clock
The analogue dry path is the reason this works: your fundamental never enters the delay circuit, so the low end stays solid while the repeats sit up in the mids where they can be heard. Keep Repeats subtle and the Tone bright so the echoes read as texture rather than mud.
How It Compares
vs the EarthQuaker Dispatch Master
The comparison that matters most, because the Dispatch Master is the pedal that replaced the Disaster Transport family in EarthQuaker’s line-up and in most people’s affections. The Dispatch Master is a delay-and-reverb combination with a smoother, more polished voice and considerably more mainstream appeal. It is a better first delay for almost anybody. The Jr. is grittier, brighter, has no reverb, and will do things at the extremes — the wet-signal boost, the raw oscillation — that the Dispatch Master will not. If you already own a Dispatch Master, the Jr. is not redundant; it is the ugly one you reach for when the polite one is wrong.
vs the EarthQuaker Avalanche Run
Not really a contest so much as a generational gap. The Avalanche Run is a stereo delay-and-reverb with tap tempo, expression control, multiple modes and Flexi-Switch. It costs several times what a used Jr. does and does several times as much. What the Jr. offers against it is immediacy — four knobs, one decision, no menu — and a fundamentally different, rougher voice.
vs the MXR Carbon Copy
The most instructive pairing, and the one Dallas Green’s tech made explicitly. The Carbon Copy is a true bucket-brigade analogue delay: dark, warm, self-filtering, 600 ms, with modulation on tap. The Jr. is a digital delay line pretending to be tape, with the filtering removed and handed to you. They land in adjacent territory from opposite directions. The Carbon Copy is more forgiving and more polite; the Jr. is brighter, louder in the wet path and more willing to misbehave. A tech being asked to make a Carbon Copy sound like a Jr. would be reaching for the internal modulation trimmers and the Regen knob and still not quite getting there.
vs the Boss DM-2W and the Maxon AD999
Both genuine analogue delays with a strong claim on the “warm vintage echo” job. The DM-2W gives you 300 ms in standard mode and 800 ms in custom mode with a cleaner repeat; the AD999 gives you a full second of BBD delay, which is close to a technical miracle. Both are quieter than the Jr. and neither can boost the repeats above the dry signal. The Jr.’s pitch against them is character and price, in that order.
vs the Boss DD-3 and the modern digital field
The Boss DD-3 is the reference point for clean, accurate, unromantic digital delay, and it is a genuinely great pedal at what it does. The DD-8, DD-200 and TC Flashback 2 add tap tempo, modes and looping. If your requirement is “a delay that does what I ask, in time, without commentary,” buy any of those instead. The Jr. is the opposite proposition: a delay with opinions.
vs the Disaster Transport Legacy Reissue
If you want the family sound with modulation, this is the one to buy new. The 2023 Legacy Reissue is the original five-knob pedal — Speed, Intensity, Mix, Repeats, Time — with a redesigned delay line, a lower noise floor, a boosted output, top-mounted jacks, Flexi-Switch on both footswitches, and two new toggles. Mod Speed offers slow, medium and fast ranges (EarthQuaker describe the medium setting as similar to the classic Deluxe Memory Man rate), and Mod Mode switches between Bend, a traditional chorus character, and Stretch, which EarthQuaker describe as “loads of pitch-stretching modulation.”
The critical detail for anyone cross-shopping: the Disaster Transport’s modulation uses a ramp wave, not the triangle or sine wave used by most modulated delays. EarthQuaker’s own description is the clearest: “Think of it as a traditional Triangle wave that falls off a cliff in mid-cycle, creating a drastic pitch bend in its wake.” That is why the family’s modulation sounds unlike a Boss CE-2 and why the reissue can produce, in the manual’s words, “bizarrely animated gradual climbs and steep drop offs.” The Jr. has none of this. If the ramp modulation is what drew you to the name, the Jr. is the wrong pedal in the family.
vs putting it in a multi-effects unit
A Line 6 HX Stomp or HX One will model a dozen delays with tap tempo and presets for the price of two used Jr.s. What it will not do is the specific interaction of an unfiltered PT2399 repeat with a wet path capable of four-times unity gain. That is not a modelling failure; nobody has modelled the Jr. because it is a discontinued small-run pedal. Buy the multi-effects for coverage and the Jr. for one sound you cannot get otherwise.
Buying Guide
The Jr. has been out of production for roughly a decade, so this is entirely a used-market conversation.
Price. Original US retail was $165. As of September 2026, listings turn up in the region of $100 in excellent used condition. That is remarkable value for a hand-built American pedal, and it is low because the Jr. lacks the two features that drive resale prices on modern delays — tap tempo and presets. You are being paid, in effect, for the inconvenience.
Identifying it. Four knobs, one footswitch, standard-format enclosure at 4.37 x 2.37 x 1.07 inches, side-mounted jacks, “Disaster Transport Jr.” on the face. If it has five knobs and two footswitches, it is the original Disaster Transport or the 2023 reissue. If it is enormous with two rows of controls and expression jacks, it is the SR. If it says “Legacy Reissue” or has top-mounted jacks, it is the 2023 model.
What to check before buying. Sweep Repeats through its full range and confirm it reaches genuine self-oscillation at maximum; a unit that will not oscillate has a problem in the feedback path. Sweep Time and listen for dropouts or stepping. Push Mix past noon and confirm the delay genuinely gets louder than the dry signal — that is the pedal’s signature and a failed wet-path gain stage is the failure that would matter most. Confirm the Tone control has real range from dark to bright. Expect some noise at extreme settings; that is normal and documented.
Warranty. EarthQuaker’s limited lifetime warranty is a company policy rather than a per-unit one and they have historically been willing to service Legacy-page pedals. Contact them through their support page rather than assuming either way on a fifteen-year-old unit.
Who should buy one. Players who already own a modern do-everything delay and want a second, uglier voice. Anyone building a fuzz-forward board who has been frustrated by delays vanishing under gain. Bassists — the analogue dry path is a real advantage. Bedroom and small-studio players who want a hand-built American pedal for a hundred dollars.
Who should skip it. Anyone who needs tap tempo, and that is a genuinely large group; it is the only entry in Equipboard’s Cons list and it is a fair one. Anyone playing to a click or switching tempos across a set. Anyone who wants trails when they bypass. Anyone who needs the modulation the family is famous for — buy the reissue. Anyone whose power supply cannot spare 100 mA on an isolated output.
Ownership Notes
The current draw is the real gotcha. Approximately 100 mA is a lot for a compact pedal — three times what the 2023 reissue draws and comparable to some digital multi-effects. A great many isolated supplies provide 100 mA per output as standard, which means the Jr. can sit right at the limit of a socket and behave erratically without ever obviously failing. Give it a 250 mA or 500 mA output if you have one. This single fact explains a disproportionate share of “my Disaster Transport is noisy” reports.
No battery, ever. There is no battery compartment and no battery option. Do not run it at higher voltages; EarthQuaker are explicit about this and the PT2399 is not tolerant.
Chain placement. EarthQuaker’s manual gives a direct instruction: “For best results, place after dirt pedals and other modulation and before any signal boosters.” Worth taking literally. Dirt first means the repeats carry the character of the distorted signal rather than distorting the repeats; boosters after means you are lifting the whole delayed image rather than driving the delay line’s input.
True bypass means no trails. Stepping on the footswitch kills the repeats instantly. If you want your delay tail to ring out over the switch-off, you need a buffered or Flexi-Switch pedal — which is precisely one of the reasons EarthQuaker moved the rest of the line onto relay switching in later years. It also means the Jr. passes signal when unpowered, which the Flexi-Switch pedals do not.
Unit variation is real. Between the PT2399’s tolerances and the hand-built, small-batch nature of EarthQuaker’s production in 2010–2015, two Jr.s may differ audibly at the extremes of the Time range. This is a characteristic, not a defect.
Frequently Asked Questions
Is the Disaster Transport Jr. an analogue delay?
No. It is a digital delay with an all-analogue dry signal path — EarthQuaker’s own phrase is “analog voiced digital delay.” Your dry tone never enters the digital circuit; only the repeats do. Several widely-circulated product descriptions describe it as having a “purely analog signal path,” which is a misreading. If you want genuine bucket-brigade analogue, look at the Carbon Copy, the DM-2W or the AD999 instead.
How long is the delay?
Approximately 30 ms at minimum to approximately 625 ms at maximum. Individual units vary slightly because of tolerances in the PT2399 chip, something EarthQuaker acknowledge openly on their reissue documentation.
Does it have modulation?
No. This is the main functional difference between the Jr. and the rest of the Disaster Transport family. The original Disaster Transport, the SR and the 2023 Legacy Reissue all have ramp-wave modulation with dedicated controls. The Jr. has four knobs and no LFO at all. If you find a source claiming the Jr. has a modulation footswitch, that source has confused it with another pedal in the family — we found exactly that error while researching this piece.
What year was it made and when was it discontinued?
Launched in 2010 according to EarthQuaker’s own blog and the copyright line on its manual, though some databases list 2011 as the start of production. It ran until roughly 2015 and now sits on EarthQuaker’s Legacy page. The entire Disaster Transport family was formally retired on 1 June 2021 when the SR was discontinued.
Why is the Mix knob so loud?
Because it is a gain control rather than a blend control. EarthQuaker designed it to boost the delayed signal to nearly four times the dry level at maximum. Unity is around noon. Above noon your repeats are louder than the note that created them. Some noise and distortion at the very top of the sweep is normal and documented in the manual.
How much power does it need?
Around 100 mA at 9V DC, 2.1 mm centre-negative, regulated, with no battery option. That is high for a compact pedal — give it an isolated output rated well above 100 mA rather than a shared or minimum-spec one. Do not run it at higher voltages.
Should I buy a Jr. or the 2023 Legacy Reissue?
The reissue if you want modulation, top-mounted jacks, a lower noise floor and a warranty on a new unit — it is a five-knob pedal with Mod Speed and Mod Mode toggles and Flexi-Switch on both footswitches, limited to 3,500 units at $219. The Jr. if you want the delay voice alone, in a small enclosure, for around a hundred dollars used. They are not the same pedal and the Jr. is not simply a cut-down reissue; it is a distinct, simpler design from thirteen years earlier.
Is it good on bass?
Yes, and better than most compact delays, for a structural reason: the all-analogue dry path means your low end never passes through the delay circuit. Keep Repeats subtle and the Tone control fairly bright so the echoes read as texture in the mids rather than competing with your fundamental.
Does it work well with fuzz?
This is arguably the pedal’s strongest single argument. EarthQuaker built it specifically to solve the problem of delays that “disappear when hitting it with dirt,” by removing the output filtering that makes most cheap digital delays sound dark. Run it after a Big Muff, a Hoof or a Tube Screamer, keep the Tone control past noon, and the repeats stay legible where a heavily-filtered delay would turn to mud.
