There is a specific sound that rock music was built on, and almost nobody can afford to make it properly anymore. A late-1960s Marshall Super Lead — a “plexi,” so named for the Perspex control panel — produces its greatest tone at a volume that will get you evicted, arrested, or sued by a venue’s noise-compliance officer. The amps themselves have drifted into five-figure collector territory. And even if you own one, hauling a 100-watt head and a 4×12 to a Tuesday-night club gig where the sound engineer wants you to turn down is an exercise in masochism.
This is the problem the Wampler Plexi-Drive Deluxe was built to solve, and it solves it with a completeness that most Marshall-in-a-box pedals never approach. It is not just a distortion circuit with a British accent. It is a full plexi preamp voicing with an active three-band EQ, a bass-boost toggle that simulates the low-end thrust of a closed-back cabinet, a bright switch for taming or brightening whatever guitar you plug in, and an entirely independent Tube Screamer-flavoured pre-gain boost on its own footswitch. Wampler’s own tagline for it is blunt to the point of arrogance: “The Ultimate Plexi Pedal.” Having examined what it actually does, that claim is closer to a technical specification than to marketing.
The Origin Story: From Modding Bench to Plexi Machine
Brian Wampler started Wampler Pedals in Indiana in 2004, initially as a pedal-modification operation and an educational resource for other builders before moving into original designs. His reputation grew from a genuinely unusual foundation for the boutique-pedal world: he wrote openly and technically about circuit design rather than hiding behind mystique about magic capacitors and secret transistors. That transparency built credibility, and the credibility built a company.
The original Plexi-Drive is one of the pedals that made Wampler’s name. Its exact birth date depends on which source you trust — Wampler’s own product page states that Brian designed the Plexi Standard in 2006, while Premier Guitar’s 2015 review of the Deluxe places the original’s introduction in 2008. The discrepancy is probably design-versus-release, and it is not important to the story except as a reminder that even manufacturer copy and major-magazine reporting can disagree on basics. What matters is that by the late 2000s, the Plexi-Drive had established itself as one of the more convincing British-amp-in-a-box pedals available, at a moment when that category was becoming crowded.
The original was a relatively simple device: a plexi-voiced overdrive with a single tone knob and a bass-boost toggle. It sounded excellent through the right amp. Through the wrong amp, you had one tone control and a prayer. That limitation is exactly what the Deluxe was designed to eliminate.
Released in 2015, the Plexi-Drive Deluxe replaced the single tone knob with an active three-band Bass/Mids/Treble EQ stack, added a bright toggle alongside the existing bass boost, and — the significant addition — built in a completely independent pre-gain boost stage on its own footswitch, voiced, in Wampler’s own tongue-in-cheek phrasing, like “that ‘valve’ screaming green overdrive with pronounced mids.” In other words, a Tube Screamer-style mid-hump boost sitting in front of the plexi circuit, inside the same enclosure, switchable on its own.
That combination — a plexi preamp with a full EQ, plus an integrated TS-style pre-boost — is precisely how thousands of guitarists actually run a real Marshall. The Deluxe just puts the whole arrangement in a 3.5-inch-wide box.
Specifications
What Every Control Actually Does
Post Gain
This is the drive control for the main plexi circuit, and it is the single most consequential knob on the pedal. At around 10 o’clock you get mild overdrive that stops just short of overt crunch — the sound of a Super Lead at conversational volume. At 1 o’clock the pedal produces genuinely natural-sounding saturation with crunchy chord voicings and glassy single notes that carry the reactivity and punch of a JTM45. Push further and you are into the territory the pedal was built for.
One critical practical note: raising Post Gain also raises overall output volume. The correct workflow is to set Post Gain for the crunch character you want first, then dial Level to match your amp’s clean volume. Doing it the other way around means constantly rebalancing.
Level
Master output for the main circuit. There is substantially more available here than unity — the pedal can slam the front end of a clean amp hard if you want it to, which is one legitimate way of getting more apparent gain and compression out of the whole rig.
Bass, Middle, Treble
An active three-band EQ stack, which is a different animal from a passive tone control. Passive tone circuits can only remove content. An active stack boosts as well as cuts, which means the Deluxe can add low end that was never there in the guitar signal, or scoop mids for a modern voicing, or push mids forward for a lead sound that cuts through a dense mix. Treat noon as roughly neutral and work outward.
The Middle control is the one that separates this pedal from most of its competition. Plexi tone is fundamentally a midrange phenomenon — that is why a cranked Super Lead cuts through a loud band without needing to be the loudest thing on stage. Being able to dial that midrange up or down is what lets the Deluxe sit correctly in front of amps that were never designed to sound British.
Pre Gain
The independent boost stage, controlled by a single knob and its own footswitch. It is voiced as a midrange-forward, Tube Screamer-flavoured overdrive that sits in front of the main plexi circuit. Its intended use is obvious the moment you step on it: leads jump out of the mix without any change to the fundamental character of your rhythm tone.
Honest limitation, and Premier Guitar flagged it in their review: the pre-gain stage has no EQ control of its own, and used entirely on its own — with the main circuit bypassed — you need to crank it to nearly 3 o’clock just to reach volume unity. It is designed to push the plexi circuit, not to function as a standalone clean boost. Buyers expecting a fully independent second overdrive channel should recalibrate their expectations; this is a boost that serves the main circuit.
Bass Boost Toggle
Simulates the low-end thump of a 4×12 cabinet. This is genuinely useful for players running open-backed combos or single-speaker amps, where the pedal can put physical weight back into a rig that does not have a closed-back cab to provide it. If you are already running a closed-back 4×12, the effect is largely redundant and can push the low end into flabbiness. It is also a legitimate tool for making a bedroom-volume setup feel bigger than it is.
Bright Toggle
Adds high-end sparkle. Its most valuable application is switching between guitars — a dark-sounding humbucker guitar can be brought forward with the bright switch engaged, and a bright single-coil guitar left flat. Premier Guitar’s reviewer went further and argued the bright switch is often a more effective way of lifting a guitar in the mix than the pre-gain boost is, specifically for pulling humbuckers out of murky low-end territory. That is a useful counterintuitive tip.
Famous Players: What Actually Checks Out
This section requires honesty, because the Plexi-Drive Deluxe is a pedal whose sound is associated with a cathedral of rock legends while its actual documented user base is comparatively small. The following distinction matters and is maintained throughout.
Confirmed Users
Yiannis Papadopoulos — the Greek fusion and shred guitarist confirms the Plexi-Drive Deluxe on his own official website’s gear page, in his own words, describing it as “My favorite drive pedal, it has great organic tone!” This is about as primary as artist confirmation gets: the artist’s own site, the artist’s own sentence, still live as of the page’s most recent update in 2025. Notably, his listed rig also includes the Wampler Ego Compressor and an Ibanez TS9 Tube Screamer, which he describes as his rhythm-tone drive — meaning he is running a real TS9 alongside a pedal that already contains a TS-voiced boost stage. That is not redundancy; that is a player who understands what each circuit does in a specific position.
Jonathan Pearce (The Beths) — documented via EarthQuaker Devices’ “Board to Death” video series, in which Pearce walks through the pedalboard used on The Beths’ 2022 US tour. In that video he describes using the Plexi Deluxe to move from his baseline overdriven tone to what he calls full-on Marshall distortion. This is the artist himself, on camera, explaining his own gain staging — a strong source, even though the video is hosted by a competing pedal manufacturer rather than a guitar magazine. Pearce’s board is also relevant for a second reason: he uses a Pro Co RAT as his dedicated soloing pedal, sitting downstream of the Plexi Deluxe. That specific stacking arrangement — plexi crunch as the foundation, RAT as the lead voice — is one of the more interesting real-world uses of this pedal documented anywhere.
Sonic Lineage, Not Confirmed Users
Wampler’s own marketing copy for the Plexi-Drive Deluxe name-checks Jimi Hendrix, Led Zeppelin, Cream and AC/DC as the artists who built the legend of the amps this pedal emulates. That is accurate as history and misleading as endorsement, so let us be precise: Jimi Hendrix, Jimmy Page, Eric Clapton and Angus Young are the reference points for the sound. None of them is a documented user of this pedal, and in Hendrix’s case the question is not even coherent — he died decades before the circuit existed.
The same applies to the other guitarists whose tones live in this pedal’s DNA: Pete Townshend, whose Super Lead stacks defined the sound of a Marshall being pushed past its design limits; Ritchie Blackmore, whose treble-boosted Marshall attack is one of the templates for hard-rock lead tone; Paul Kossoff, whose vibrato and plexi-driven sustain remain a reference for expressive rock playing; Tony Iommi, whose early Sabbath tone came from Laney and Marshall heads pushed hard with a treble booster; and Mick Ronson, whose wall of Marshall distortion behind Bowie is one of the most instantly recognisable rhythm sounds in glam rock. Owner reviews on Wampler’s own site independently report using the Deluxe to get convincing early Iron Maiden tones of the kind Dave Murray and Adrian Smith built and Zeppelin sounds — which is fan testimony rather than artist endorsement, but it is at least real-world evidence of what the circuit does.
The honest summary: two well-documented professional users, a broad reputational footprint among working and amateur guitarists, and a genealogy that reaches back to nearly every important British rock tone of the late 1960s and 1970s. That genealogy is real. The endorsement roster is modest. Both things can be true.
Tone Recipes and Settings
Late-’60s Super Lead Crunch
Post Gain 11 o’clock, Level to taste for unity, Bass noon, Middle 1 o’clock, Treble 1 o’clock, Bass Boost off, Bright off, Pre Gain disengaged. This is the fundamental voice of the pedal — the sound of a plexi turned up to where it starts to break up but has not yet committed to distortion. Use your guitar’s volume knob for cleanup; the circuit responds to it properly.
AC/DC Rhythm
Post Gain 12 to 1 o’clock, Bass noon, Middle 2 o’clock, Treble 1 o’clock, Bass Boost off, Bright off. The critical instruction here is restraint: the classic Australian rhythm tone has far less gain than most players assume. Get the crunch from Post Gain around noon, push the midrange, and let the pick attack do the work. If it sounds too clean, you are probably close to correct.
Zeppelin Lead
Post Gain 2 o’clock, Bass 1 o’clock, Middle 2 o’clock, Treble noon, Bass Boost on, Bright off, Pre Gain engaged at 11 o’clock. The pre-gain stage adds the midrange focus that lifts a solo above a dense arrangement, and the bass boost provides the low-end weight that a Super Lead into a 4×12 delivers naturally. Neck pickup.
Early Iron Maiden Gallop
Post Gain 3 o’clock, Bass noon, Middle 2 o’clock, Treble 2 o’clock, Bright on, Bass Boost off, Pre Gain engaged at 1 o’clock. Both drive stages running gives you the saturation and midrange projection required for fast alternate-picked and galloping rhythm figures without losing note separation. Owner reports on Wampler’s own site specifically cite this territory as reachable with the pedal maxed out.
Glassy Gritty Clean
Post Gain 8 to 9 o’clock, Level 2 o’clock, Bass 11 o’clock, Middle noon, Treble 1 o’clock, Bright on. At very low Post Gain settings with Level pushed high, the Deluxe functions as a slightly gritty preamp that adds British colouration without meaningful distortion. This is an underused setting and it is excellent for adding character to a sterile clean amp.
Modern Country Drive
Post Gain 10 o’clock, Bass 11 o’clock, Middle 11 o’clock, Treble 2 o’clock, Bright on, Bass Boost off. Single coils. A tighter, brighter, lower-gain setting that cleans up completely with the volume knob — closer in function to a transparent drive than to a Marshall stack, and a reminder that the EQ stack makes this pedal considerably more versatile than “plexi in a box” suggests.
Solo Boost on Top of Rhythm
Set the main circuit for your rhythm sound. Set Pre Gain between 11 o’clock and 1 o’clock, and engage it only for leads. Because the boost is pre-gain rather than post-gain, it increases saturation and midrange focus as well as volume — this is a tonal change, not just a level change, which is the entire point.
All settings below assume a clean amp platform at moderate volume, humbuckers unless otherwise noted, and clock positions from fully counter-clockwise (7 o’clock) to fully clockwise (5 o’clock). Noon is neutral on the EQ.
How It Compares
Against Its Own Family
The Wampler distortion line is unusually well differentiated, and the Plexi-Drive Deluxe occupies a specific spot in it. The Wampler Pinnacle Deluxe V2 is the other Marshall-adjacent pedal in the range, but it is aimed at a later era — brown sound, JCM800 territory, higher gain, tighter low end. The Plexi-Drive Deluxe is earlier, looser, more open, and more responsive to picking dynamics. If you want Van Halen, buy the Pinnacle. If you want Cream, Zeppelin and AC/DC, buy the Plexi-Drive Deluxe.
The Wampler Pantheon Deluxe is a Bluesbreaker-derived dual-channel drive — smoother, more compressed, considerably more polite. The Wampler Belle Overdrive is a transparent full-frequency drive built on ODR-1 DNA, designed to preserve your amp’s character rather than replace it. The Wampler Paisley Drive Deluxe is a country-focused signature dual drive. The Wampler Tumnus is a Klon-style transparent boost. Only the Plexi-Drive Deluxe is trying to replace your amplifier’s voice entirely.
Against Digital Plexi Emulation
The most interesting modern comparison is the Universal Audio UAFX Lion ’68 Super Lead, which models the same amplifier using DSP, complete with cabinet and microphone emulation and direct output. The Lion does things the Wampler cannot: it produces a fully realised amp-and-cab sound direct to a mixing desk or interface, with no amplifier required. The Wampler does things the Lion cannot: it costs less, it has zero latency, it requires no menus or app, and it interacts with a real tube amp’s power section in a way that a modelling device placed in front of that same amp does not. They are complementary rather than competitive, and plenty of players own both.
Against Traditional Overdrives
An Ibanez TS9 and a Plexi-Drive Deluxe are not doing the same job. The TS9 sculpts and pushes an amp that is already producing the fundamental tone. The Plexi-Drive Deluxe supplies the fundamental tone itself. This is why running both makes sense, and why Yiannis Papadopoulos does exactly that. The Boss BD-2 Blues Driver occupies similar amp-like territory but with far less gain and a fundamentally different, more transparent voicing. The Boss DS-1 is a hard-clipping distortion with a distinct mid-scoop character and no ambition to sound like any particular amplifier.
Against a Real Marshall
A Marshall DSL5CR or similar small-format tube amp gives you real valve compression, real power-amp sag, and real speaker interaction at manageable volume. What it does not give you is the specific voicing of a late-’60s Super Lead, and it does not travel to a backline gig in your gig bag. The Plexi-Drive Deluxe’s most compelling professional argument is portability: it turns whatever clean amp is waiting for you at a festival, a fly date or a rehearsal room into a plausible plexi. Premier Guitar’s review specifically noted how effectively it lent plexi character to a 6L6-powered Fender Twin Reverb, which is about as far from an EL34 Marshall as a mainstream amp gets.
Buying Guide
Who Should Buy This
Players whose core sound is British classic rock and who cannot or will not run a real plexi. Guitarists on fly dates and backline gigs who need their tone to survive whatever amp they are handed. Home recordists who need cranked-Marshall character at apartment volume. Anyone running a clean-platform amp — a Twin Reverb, a Deluxe Reverb, a Princeton, a modern pedal-platform amp — who wants a British voice available on a footswitch. And any player who wants a rhythm and lead arrangement in one enclosure, since the independent pre-gain boost genuinely covers that job.
Who Should Look Elsewhere
Players wanting modern high-gain metal — this is a plexi circuit and it will not deliver tight, scooped, downtuned modern metal tones no matter how far you push it. Players who need a truly independent second drive channel rather than a boost that serves the main circuit. Players wanting a transparent overdrive that preserves their amp’s character rather than replacing it, who should look at the Belle or the Tumnus. And players on a tight budget, since $239.97 MSRP places this firmly in premium boutique territory.
New Versus Used
The pedal has been in continuous production since 2015, so the used market is reasonably well supplied. Expect roughly $130 to $175 for a clean used example against $200 to $240 new — a meaningful saving, with the significant caveat that Wampler’s five-year warranty applies to the original purchaser with a dated sales receipt.
On versions: you will see the pedal listed as “V2,” and you will encounter units with different footswitch labelling — some marked Pre Gain and Post Gain, others marked Boost and Bypass. According to Wampler, the circuit is identical across these; the changes are graphics and labels only. This is not a case where you need to hunt for a particular revision. Buy on condition and price, not on version number.
Ownership Notes
Power. The Deluxe draws between 22mA at 9V and 34mA at 18V. Any competent isolated supply handles it easily. It also accepts a 9V battery, and the LED flashes three times when the battery is running low — a genuinely useful warning that many pedals do not provide. As with all Wampler pedals that support 18V operation, running at the higher voltage increases headroom and gives a more open, dynamic feel. It is worth trying if your supply has an 18V output.
Bypass. Relay true bypass. Your signal is entirely out of the circuit when disengaged, which is good for tone purity and less good for long cable runs, since there is no buffer. If you run more than about 20 feet of cable in total, put a buffer somewhere in the chain. Relay switching is soft-touch and reliable under heavy footswitch use, though the relay click can be audible in very quiet stage environments.
Placement. The Plexi-Drive Deluxe belongs early in the chain, in the drive section, after wah, compression and filter effects and before modulation, delay and reverb. Because it is true bypass, fuzz pedals can sit either side of it without impedance issues — though a fuzz almost always wants to be first in line.
Stacking. This pedal is a platform, not a terminus. Putting another drive after it, as Jonathan Pearce does with a RAT, gives you a second gain tier for solos that sounds different rather than merely louder. Putting a Tube Screamer before it tightens the low end and pushes the midrange further forward than the internal pre-gain boost does, since the TS has its own tone control.
Set the gain stages separately. Dial the main circuit to your rhythm sound with the pre-gain disengaged. Only then set the pre-gain level. The temptation to set both together produces a lead tone that is either inaudible or deafening.
Bass Boost is amp-dependent. On a closed-back 4×12 it will usually be redundant or actively counterproductive. On an open-backed combo it can transform the pedal. Test it on your actual rig before deciding whether it is useful.
Frequently Asked Questions
Is the Wampler Plexi-Drive Deluxe worth the price over the standard Plexi-Drive?
It depends entirely on how much tonal shaping you need. The standard Plexi-Drive has a single tone control, which is sufficient if it happens to match your amp and guitar. The Deluxe adds an active three-band EQ, a bright toggle and an independent pre-gain boost footswitch. If you play through one amp you know well and the standard version already sounds right, the Deluxe’s extra features are luxuries. If you play through backline amps, switch between guitars, or need a footswitchable lead boost, the Deluxe is the version that actually solves those problems.
Will it work with a solid-state amp or a modeller?
Yes, and this is one of its stronger use cases. The pedal supplies the distortion character itself rather than relying on the amp’s overdrive, so a clean solid-state amp or a clean modeller patch works as a platform. What you will not get is the interaction between the pedal and a real tube power section — the compression and sag that a driven valve amp contributes. Expect the result to feel slightly stiffer than through a tube amp, and compensate with the bass boost and a touch more Post Gain.
Can I use the pre-gain boost on its own as a clean boost?
Technically yes, practically not really. Premier Guitar found that with the main circuit bypassed, the pre-gain stage needs to be pushed to nearly 3 o’clock just to achieve volume unity, which leaves very little usable range above that. The boost was designed to drive the plexi circuit, not to function independently. If you need a genuine standalone clean boost, use a separate pedal.
Is 18V operation actually better than 9V?
Different rather than universally better, but most players prefer it. At 18V the circuit has more headroom, which produces a more open, less compressed feel with greater dynamic range and cleaner peaks. At 9V the pedal is slightly more compressed and immediate. Current draw rises from 22mA to 34mA, which any quality supply handles. If you have an 18V output available, try it — the difference is audible.
How does it compare to the Wampler Pinnacle Deluxe V2?
They target different Marshall eras. The Plexi-Drive Deluxe is a late-1960s Super Lead and JTM45 voice: looser, more open, more dynamically responsive, lower maximum gain. The Pinnacle Deluxe V2 is aimed at the brown sound and JCM800 territory: tighter, higher gain, more aggressive, with a Vintage/Modern switch and a SAG control that the Plexi-Drive Deluxe does not have. Neither replaces the other. If your reference points are Cream, Zeppelin and AC/DC, the Plexi-Drive Deluxe is the correct pedal. If they are Van Halen, Rhoads and 1980s Marshall lead tone, the Pinnacle is.
Do I need a noise gate with this pedal?
Usually not at moderate gain settings. At maximum Post Gain with the pre-gain boost engaged and single-coil pickups, you will hear the noise floor rise — as you would with any high-gain circuit or a real cranked plexi. If you play in that territory regularly, a noise gate is a reasonable addition, but the pedal is not unusually noisy for its type. Isolated power and good-quality cabling solve most complaints before a gate becomes necessary.
What is the difference between the V1 and V2 Plexi-Drive Deluxe?
According to Wampler, nothing that affects sound. The differences are cosmetic — graphics and footswitch labelling. Some units label the switches Pre Gain and Post Gain, others label them Boost and Bypass, but the circuit underneath is the same. Buy on condition and price rather than searching for a specific revision.
Does it clean up with the guitar’s volume knob?
Yes, and well. This is one of the pedal’s defining characteristics and a large part of why it earns the plexi comparison — a real Super Lead is exquisitely responsive to guitar volume, and a Marshall-in-a-box pedal that does not clean up is missing the point. Premier Guitar’s reviewer specifically recommended setting Post Gain higher than you think you need and using the guitar’s volume control to manage gain, describing that approach as affording greater control than adjusting the pedal itself. It is the correct way to use this pedal.
Is it a good pedal for recording direct?
On its own, no — it has no cabinet simulation and no direct output, so plugging it straight into an interface produces the harsh, fizzy top end that all uncabineted distortion produces. Paired with a decent impulse response loader or a cab-sim pedal, it records extremely well, and that combination gives you an analogue drive circuit feeding a digital cabinet, which many engineers prefer to fully digital chains. If you want an all-in-one direct solution instead, a device like the UAFX Lion is the more appropriate tool.
