In 1989, a young German named Reinhold Bogner arrived in Los Angeles with a modified Marshall under his arm, six hundred dollars in his pocket, and an obsession with tone that bordered on religious. Within three years, he had built an amplifier so flexible, so dynamically alive, and so musically ambitious that the boutique market would spend the next three decades trying to answer it. That amplifier was the Bogner Ecstasy. The 101B — the current EL34-powered flagship — is the amp Bogner has been refining ever since. It is not the loudest boutique head on the market, not the simplest, and certainly not the cheapest. But it remains, by almost any measure, one of the most sophisticated guitar amplifiers ever put into production, and the story of how it got there is worth knowing before you touch a single knob.
Reinhold Bogner and the Making of a Legend
Bogner grew up in southern Germany tinkering with his father’s spare tube-radio parts, trying to recreate the sounds of Angus Young and Gary Moore with whatever he could scrounge. By the time he was a young man, his reputation as a modifier had already spread through local musician circles. On the advice of Kansas guitarist Rich Williams, Bogner made the move to Los Angeles in 1989, carrying a heavily modified JCM 800 as his calling card. The L.A. studio scene in the late 1980s was hungry for exactly what he was selling: boutique-level hot-rodding in a city where session guitarists like Michael Landau and Steve Stevens needed sounds that no production amp could provide.
Through gear-rental entrepreneur Andy Brauer, Bogner found himself working on amplifiers for a remarkably well-connected client list almost immediately. Producer Dave Jerden introduced Jerry Cantrell to a Bogner-modified Marshall for Alice in Chains’ debut album Facelift (1990), and the resulting tone — that mid-forward, gainy, slightly dark shove heard on tracks like “We Die Young” and “Man in the Box” — created immediate buzz around Bogner’s name. Cantrell himself has described it in his own words: “The first couple records that we did, Facelift and Dirt, was basically a Marshall modified by Bogner, and then of course I started picking up some of his amp stuff because I liked the mods that he was doing, so used the Fish for many years.” The key phrase there is “Fish” — Bogner’s famous rack-mounted all-tube preamp. Cantrell’s relationship with Bogner has always been with the Fish preamp and custom-modded Marshalls, and his current 2024 touring setup confirms it: a Bogner Fish All Tube Preamp running into Fryette power amps. Not an Ecstasy 101B — a fact worth nailing down before we discuss the amp itself.
Meanwhile, Bogner developed the Triple Giant, a three-channel rack-mounted tube preamp designed at the request of session guitarist Joey Brasler in 1989. Only twenty-five were built in 1989–90, but the Triple Giant demonstrated something Bogner had been working toward: a single device that could convincingly cover clean, crunch, and high-gain territory with real tube response at every setting. Preamps were fashionable in the late-rack era, but Bogner quickly realized their limitation: separating the preamp from the power amp removes the interplay between the two sections that gives tube amplifiers their organic feel. He spent a year developing a standalone amplifier that preserved that interaction while matching the tonal range of the Triple Giant. The result, released in 1992, was the Ecstasy.
From 100B to 101B: The Model Family Decoded
The Bogner Ecstasy has carried four designations across its production history, and the nomenclature matters. The original models were the 100A and 100B. The “A” designation means American — four 6L6 power tubes, producing the tight low end and glassy top characteristic of American-voiced circuits. The “B” designation means British — four EL34 tubes, which push a richer midrange, a rounder low-end bloom, and a more vocal, cutting high-frequency response. Only approximately 100 units of the 100B were ever built, making them genuinely rare objects on today’s used market.
The 101A and 101B are the revised versions introduced in 1997. Rather than changing the fundamental circuit, Bogner expanded the options architecture: the Class A/AB switch, individual line outputs for each channel, metal grille option, and assignable speaker cabinet switching all moved from baked-in features to customer-selectable additions. The “101” designation also reflects ongoing circuit refinements and updated component choices. In 2001, a Classic variant was introduced with a chrome front panel and what Bogner describes as a more open, organic feel — a nod to the earliest 100B units for players who wanted that particular character.
The 101B is, in the current range, the EL34-powered flagship. Its sibling the 101A runs 6L6s for the tighter, more scooped American voice. Both heads are built one at a time by hand in Bogner’s Los Angeles facility, using hand-wired point-to-point construction with custom transformers.
Specifications
A few specs deserve explanation because they shape the playing experience more profoundly than a spec sheet suggests. The 3-position Pre-EQ switches on each channel are not tone controls in the conventional sense — they select pre-set EQ curves applied before the gain stage, letting you voice the character of each channel between three distinct personalities. Combined with the Gain Structure switch on channels 2 and 3, each channel effectively becomes three different animals, giving the amp the sonic palette its reputation promises.
The Plexi Mode on channel 3 is one of the Ecstasy’s most discussed features. Engaging it opens the negative feedback loop in the power section, softening the compression and tightening the dynamics in a way that sounds — and feels — like a less-compressed vintage Marshall at the edge of breakup. It is a genuinely different amplifier response, not a subtle shift, and it fundamentally changes how the guitar interacts with the power stage.
The Old/New switch alters the attack character across the amp. Old mode delivers a softer, more saturated, forgiving response; New mode tightens the pick attack and sharpens transients. Experienced players typically use Old for leads and New for rhythm when pushing heavier gain.
The Excursion switches control speaker cabinet dampening via the power section’s output impedance loading. Tight feel suits heavy rhythm playing where definition and note separation are critical. Loose feel adds sag and bloom, pushing the power section into slight compression — the classic scenario for singing lead tones at moderate master volumes.
Famous Players: What the Spreadsheet Says vs. What the Primary Sources Confirm
The Bogner Ecstasy carries one of the most mythologised artist rosters in boutique amp history, and the mythology creates its own fog. Let’s cut through it by examining each major claimed connection against the evidence.
Steve Lukather — Fully Confirmed, 101B Specifically
Steve Lukather’s connection to the Bogner Ecstasy 101B is not ambiguous. His own official website states it plainly: “The heart of Lukather’s equipment are two Bogner-Ecstacy-101B-Halfstacks. Luke is using all three Ecstacy channels for his basic sounds: clean, crunch and lead. The overdrive is only coming from the Bogner.” He runs the two 101B heads in a stereo configuration with Celestion Vintage 30-loaded 4×12 cabinets, routing stereo time-based effects (Strymon BlueSky, Strymon Lex Rotary) through the effects loop return of the second head. One amp drives the main signal; the second amp receives the stereo return, giving him a wide-open studio sound on stage. Lukather has also appeared in official Bogner promotional materials, and his 2013 collaboration with the brand produced a dedicated video. If you want to hear the 101B at its most refined for session-level clean and crunch work, Luke’s output with Toto is the primary case study: detailed, articulate, dynamically rich, and absolutely relentless about transparency.
Steve Vai — Ecstasy Yes, But 100A (Not 101B), and a Loaner
Steve Vai’s documented Bogner Ecstasy connection is real but requires precision. During the Sex & Religion touring period and the Alien Love Secrets recording era (mid-1990s), Vai used a Bogner Ecstasy — specifically the 100A (the American-voiced 6L6 version), not the 101B. The amp was a loan from Bogner, not Vai’s own purchased instrument. Vai used the Ecstasy’s preamp section running into a VHT 2150 stereo power amplifier rather than the Ecstasy’s own power section, which is a meaningful distinction for anyone trying to recreate that exact tone. The mid-1990s Vai sound attributed to the Ecstasy should be understood as: Ecstasy 100A preamp → VHT power section → custom cabs. His primary amps in other eras have been Carvin and custom rigs. The 101B association is a frequently repeated simplification.
Jerry Cantrell — Bogner Yes; Ecstasy 101B, No
The confusion here is genuine and understandable because Cantrell and Bogner have a long, documented relationship — it just doesn’t involve the Ecstasy. Bogner modified the Marshall amp Cantrell used for the foundational Alice in Chains records Facelift and Dirt. Cantrell then adopted the Bogner Fish, a separate product entirely: an all-tube rack preamp, not a standalone amplifier head. His 2024 PG Rig Rundown is unambiguous: a Bogner Fish All Tube Preamp running into Fryette Two/Ninety/Two and Fryette LX II stereo power amplifiers. That setup has driven his live sound for years. The Friedman JJ-100, his signature amp released with Friedman Amplification, is a separate chapter — not Bogner at all. Mentioning Cantrell in the context of the Ecstasy 101B is, at best, a brand-level association; at the SKU level it does not hold up.
Eddie Van Halen — Early Bogner Customer; Not an Ecstasy Connection
Eddie Van Halen was among Bogner’s earliest customers. He purchased one of the custom modified Marshall amplifiers Bogner had built — accounts suggest EVH paid $600 for it, the exact amount Bogner had arrived in L.A. with. Bogner also sold Van Halen a “hand-wired one-off custom amp” during the early period. But this relationship predates the Ecstasy by several years: those transactions happened in 1989–1991, the Ecstasy didn’t exist until 1992, and by 1992 Eddie Van Halen’s signature tone was fully defined by the Peavey 5150, the amplifier he co-designed with Peavey. No primary source — no rig rundown, no interview, no tech documentation — places Van Halen on an Ecstasy 101B or on an Ecstasy at all. His early connection to Bogner is about Fender Showman-based custom builds and modded Marshalls. The Ecstasy is a separate timeline.
Mark Tremonti — Studio Confirmed
Mark Tremonti has been open about his use of the Bogner Ecstasy 101B in the studio for lead tones, noting that for live use he finds it “a little thin” compared to his Mesa/Boogie rigs, but praising it specifically for the detail and articulation it brings to recorded guitar. He has brought both his Ecstasy and his Bogner Shiva to recording sessions for Creed and Alter Bridge material. His current live rigs tend to be dominated by Mesa/Boogie and the Tremonti signature amps, but the Ecstasy’s studio role in his career is documented in multiple interviews.
Walter Becker — Documented 100B Owner
Vintage Guitar magazine has documented that Steely Dan’s Walter Becker (1950–2017) owned and played a Bogner Ecstasy 100B — one of the approximately 100 original EL34 models built before the 101 revision. Becker’s connection to the Ecstasy is real, though his profile in rock guitar circles is obviously very different from the other players mentioned here. It’s a useful data point for understanding the Ecstasy’s versatility: a player best known for complex jazz-adjacent chord work finding the amp’s clean and crunch channels compelling is testament to how far the Ecstasy’s tonal range extends beyond its reputation as a high-gain rock machine.
Tone Recipes and Settings
1. Classic Clean Toto Lead (Lukather Reference)
Channel 1 (Clean). Gain at 3–4 o’clock (Boost engaged for leads). Pre-EQ in position 2 (mid-forward). Bass 11 o’clock, Middle 1 o’clock, Treble 12 o’clock. Presence (assignable) at 1 o’clock. Excursion: Loose. Old/New: New. Characteristics: full, slightly compressed cleans with harmonic richness and sparkle. Pick attack is immediately present without being brittle. Volume the guitar back slightly and the EL34s do the rest. Works best into a Celestion Vintage 30 or G12M-65 Creamback; avoid modern speakers — they make the top end too forward.
2. EL34 Crunch — Vintage British Reference
Channel 2. Gain at 9–10 o’clock. Pre-EQ position 1. Gain Structure switch engaged. Bass 10 o’clock, Middle 1 o’clock, Treble 12 o’clock. Presence 12 o’clock. Old/New: Old. Excursion: Medium. The Pre-EQ at position 1 gives an inherently bright, open voicing reminiscent of a modded JTM 45. Think midrange punch with a pick attack that sings rather than spits. Classic rock rhythm and early hard rock lead territory. Compare: Marshall JTM45-2245 sits in this same tonal neighbourhood but without the gain range or channel options.
3. High-Gain Lead — Singing Saturation
Channel 3. Gain at 2 o’clock. Pre-EQ position 3. Gain Boost OFF (add only if needed). Plexi Mode OFF. Bass 11 o’clock, Middle 12 o’clock, Treble 11 o’clock. Presence (fixed) 1 o’clock. Old/New: Old. Excursion: Tight. This is the setting heard on countless L.A. studio sessions in the 2000s — a soaring, sustained lead tone with EL34 midrange push and controlled compression. The key is keeping the Treble from getting harsh while allowing the Middle to carry the harmonic content. Add a light overdrive pedal (Ibanez TS808) in front to add sustain without mud.
4. Plexi Mode — Power Section Open
Channel 3. Gain at 12–1 o’clock. Plexi Mode ON. Pre-EQ position 2. Master volume raised slightly higher than usual (the amp needs power-section engagement to achieve this voicing correctly). Old/New: New (counterintuitively, this sharpens transient response when the power section is already soft). Excursion: Loose. The experience here is genuinely different from any other position on the amp — the power section stops compressing in the usual way and you hear the notes bloom rather than sustain. Single-note runs have more definition; chords have more air. Think late-1960s vintage Marshall running hard. This is not a high-gain setting; at this gain level the amp craves dynamics from your pick.
5. Class A Mode — Compression and Sag
(Requires the optional Class A/AB switch.) Class A engaged. Channel 2, Gain at 8–9 o’clock. Old/New: Old. Excursion: Loose. Presence (assignable): 11 o’clock. The amp’s character changes substantially in Class A: earlier onset compression, a softer but more enveloping saturation, and a pleasing sag under hard picking that tightens up as notes sustain. This is the 101B’s “coffee shop at 11 AM” setting — not aggressive, just musical, with a dynamic range that responds to how hard you play. Running a Stratocaster into this setting produces sounds that are essentially unattainable from a cathode-biased single-ended design at this power level.
How It Compares
vs. Soldano SLO-100
The Soldano SLO-100 is the Ecstasy’s closest historical rival, and the comparison reveals two fundamentally different design philosophies. The SLO-100 is a two-channel amp optimised for the high-gain rock sound: the Overdrive channel is one of the most natural, saturated, and feed-forward guitar tones in the boutique world, and it does that one thing with remarkable purity. The Ecstasy 101B is a three-channel amp designed to cover the full spectrum from clean through crunch to lead, and it does so with a more complex control architecture. The SLO-100 is simpler to get great sounds from; the Ecstasy rewards players who want to spend time understanding what each switch actually does. For pure high-gain rock, the SLO-100 has a slight edge in immediacy. For versatility and tonal range, the Ecstasy is in a class of its own.
vs. Marshall JCM800 2203
The Marshall JCM800 2203 is the original of the species that Bogner set out to improve upon. The JCM800’s single channel covers a wide gain range via the preamp gain control, but it has no footswitching between defined voices, no Pre-EQ options, and no equivalent of the Ecstasy’s power section voicing switches. The JCM800 is immediate, loud, punchy, and brutal in the best way. The Ecstasy 101B offers all of those qualities plus the ability to move between clean, crunch, and lead without touching the front panel. On pure rock authority, they are comparable. On versatility and studio-ready refinement, the Ecstasy wins by a significant margin — at five times the price.
vs. Mesa/Boogie Dual Rectifier
The Mesa/Boogie Dual Rectifier is the Ecstasy’s closest American-made rival at the boutique-adjacent price point. Where the Dual Rectifier runs into compression earlier and produces a thick, saturated, almost wall-of-sound character, the Ecstasy 101B tends toward more transparency and note definition even at high gain. The Dual Rec is the more brutal amp; the Ecstasy is the more articulate one. A rhythm guitarist in a dense mix playing drop-tuned heavy metal probably wants the Dual Rec. A guitarist who needs to be heard in detail — who plays complex chord voicings, jazz-influenced bends, or session-level clean-and-crunch — probably wants the Ecstasy.
vs. Friedman BE-100 Deluxe
Dave Friedman built his reputation modifying Bogner and Marshall amps, so the Friedman BE-100 Deluxe is in many ways the spiritual descendant of exactly the circuit tradition the Ecstasy established. The BE-100 Deluxe is slightly more brutal at high gain, with a direct Plexi-derived voice on the Clean channel that some players find more immediately usable than the Ecstasy’s clean architecture. The Ecstasy’s Pre-EQ switches and Old/New voicing options give it more tonal variation than the BE-100 Deluxe’s gain-and-channel layout, but the Friedman is arguably more intuitive to dial in. At similar prices (new BE-100 Deluxe ~$3,999, new Ecstasy 101B ~$3,818), they occupy the same tier with meaningfully different personalities.
vs. Bogner Überschall
Within the Bogner range itself, the Überschall sits at the opposite philosophical pole from the Ecstasy. The Überschall was designed specifically in response to demand for a heavy, bass-forward, extreme-gain amp — an amp Bogner himself initially resisted building because the sound didn’t personally appeal to him. The result became a nu-metal and progressive metal staple (Periphery, Killswitch Engage-adjacent players, djent early adopters). The Ecstasy 101B was designed to be everything: clean, crunch, lead, voiced for the widest possible player range. The two amps share a builder and a build philosophy (handmade, point-to-point, Los Angeles) but occupy completely different tonal territories.
Buying Guide
The Ecstasy 101B is available new through authorised Bogner dealers, though production runs are small and waiting lists are not uncommon. New pricing sits around $3,818 for the standard 101B in Comet Black; the optional Class A/AB switch ($265), metal grille ($185), and individual channel line outs ($100) add to that total. The 20th Anniversary 101B model (released around 2012) featured upgraded components and limited cosmetic options; used examples command a meaningful premium over standard production units.
The used market for the 101B runs broadly from $2,000 to $2,700 for standard production units in good condition, with some clean examples pushing toward $3,000. Early 100B units (approximately 100 made) are genuinely rare and priced accordingly — expect to pay considerably more for a verified 100B, and verify the serial number against the model designation before purchasing. The 101B vs. 100B distinction is not always correctly identified in listings, and sellers are not always aware of which they have.
Things to check when buying used: confirm the power tubes (101B should have four EL34s, not 6L6s — a tube swap is common but changes the amp’s character significantly), verify which optional features are installed (the Class A/AB switch may or may not be present), and check that the effects loop switching operates correctly (the series/parallel mode control is a tube-circuit switching function, and intermittent operation can indicate socket or tube issues). The hand-wired construction makes the amp generally repairable by competent technicians, but Bogner’s point-to-point work is dense — factor in a technician familiar with boutique hand-wired circuits.
Ownership Notes
The Ecstasy 101B is a power-hungry amplifier that benefits from being run at reasonable master volumes. At very low volume, the EL34s don’t reach their working temperature range and the amp can sound flat and uninspiring. Players who primarily work at bedroom levels should consider whether a boutique head at this power level is the right choice, or whether a lower-wattage equivalent (the Bogner Shiva, for example, at 80W) might serve better. The half-power switch (which drops the amp to approximately 25W) helps, but the character at 25W is meaningfully different from 100W — thinner low end, less power-section compression.
The shared EQ section is the amp’s one significant limitation for live use. Bass, Middle, and Treble controls are global across all three channels, which means that if your clean tone requires a bright EQ curve and your lead tone needs a darker setting, you’re either compromising both or relying on the Pre-EQ switches to compensate. Experienced players build their rig around this constraint — a buffered overdrive pedal in front can adjust the EQ curve per channel without touching the amp’s controls, effectively giving each channel its own pre-eq via the signal chain.
The tube-buffered effects loop is genuinely transparent, which the “truly transparent” claim rarely is on cheaper amps. Bogner chose tube buffering deliberately to maintain the feel of the preamp signal. Modern drives, modulation, and reverb all behave predictably in it. The series/parallel mix control is particularly useful for players running reverb and delay who want to blend wet signal without losing the dry amp character.
Budget for a tube replacement approximately every two to three years of regular gigging use. The EL34 tubes are widely available and competitively priced; the 12AX7 preamp tubes last considerably longer. When replacing power tubes, have a qualified technician bias the amp — the 101B requires correct bias for the EL34s to perform properly, and factory bias settings matter more on a hand-wired design than on a production PCB amp where component tolerances are tightly matched.
FAQ
What is the difference between the Bogner Ecstasy 101A and 101B?
The 101A uses four 6L6 power tubes (American voicing: tight lows, glassy high end) while the 101B uses four EL34 power tubes (British voicing: richer midrange, rounder low-end bloom). The preamp circuit is essentially identical between the two models. The tonal difference is genuine and significant — the 101B has the more vocal, mid-forward character associated with classic British amps; the 101A is tighter and more scooped.
What is the difference between the Bogner Ecstasy 100B and 101B?
The 100B was the original 1992 production model, with approximately 100 units built. The 101B is the revised version introduced in 1997, featuring an expanded options architecture (Class A/AB switch, individual channel line outs, metal grille, assignable speaker switching) and ongoing circuit refinements. The 100B’s rarity makes it collectible; the 101B’s optionality makes it more versatile. Sonically, experienced players note the 100B has a slightly more open, organic feel — Bogner addressed this in the Classic variant introduced in 2001.
What does the Plexi Mode switch do on the 101B?
Plexi Mode opens the negative feedback loop in the power section, removing the corrective damping that normally tightens transient response and controls low-end bloom. The result feels like a vintage Marshall running without feedback — softer attack, more dynamic range, and a quality some players describe as “alive” in a way that fixed-feedback designs are not. It is most effective at moderate to higher master volumes where the power section is actually contributing to the sound.
Is the Bogner Ecstasy 101B good for metal?
It depends on the metal. The Ecstasy 101B has substantial gain on the Lead channel and excellent note definition and separation — qualities that make it excellent for technical metal, progressive metal, and melodic high-gain work. For extreme modern metal, djent, or drop-tuned heavy genres, the Bogner Überschall is a better-matched tool; the Ecstasy does not produce the same saturated wall of bass-heavy distortion. Players like Tremonti who use it for studio leads understand that its strength is in articulation, not raw brutality.
How many channels does the Bogner Ecstasy 101B have, and how many sounds can you get from it?
Three channels, but the effective sound palette is substantially larger. Each channel has a 3-position Pre-EQ switch that selects a different voicing curve. Channels 2 and 3 have a Gain Structure switch. Channel 3 has the Plexi Mode switch and Gain Boost. The Old/New switch and Class A/AB switch (optional) apply globally. Running the math: three channels × three Pre-EQ positions × two Gain Structure positions on channels 2 and 3 × Plexi Mode on/off × Old/New on/off = dozens of distinct tonal combinations. This is the amp’s defining characteristic and the reason its manual requires careful reading before the first session.
Why does the 101B have two Presence controls?
One Presence control is permanently active; the second is footswitch-assignable, meaning you can kick it in for a lead boost without changing the overall channel settings. It is a practical performance tool: you dial in your rhythm Presence setting for the room, then engage the assignable Presence for solos to cut through a loud mix. Some players also use the assignable Presence as a brightness/air boost when running into darker cabinets.
What speakers work best with the Bogner Ecstasy 101B?
The Ecstasy 101B was voiced to work with a wide range of speakers, but Celestion Vintage 30s are the most commonly documented match — Lukather’s Bogner halfstack setup uses V30s, and their mid-forward character complements the 101B’s already detailed midrange without doubling up in the same frequency range. Celestion G12M-65 Creambacks soften the top end and add warmth, making them a good choice if the room or channel is running bright. Avoid very efficient, high-watt modern speakers (Celestion G12T-75, etc.) that tend to push the top end and thin the mids — the 101B doesn’t need that kind of efficiency, and the combination can get harsh at the Gain levels the amp is capable of.
Is the Bogner Ecstasy 101B still in production?
Yes. Bogner continues to hand-build the Ecstasy 101B in Los Angeles. Production volumes are small by necessity — these are individually hand-wired amplifiers assembled by a small team — and lead times for new orders can extend to several weeks or longer depending on demand. Unlike many boutique amplifiers that have moved offshore or increased production volume at the expense of hand-wiring, Bogner has maintained the same build approach since 1992. That consistency is part of what the price is paying for.
