The Mesa Boogie Mark III era came to an end. 1995 saw Trey move to a modular preamp/power amp architecture for the first time, adding rotating speaker textures, tremolo, and univibe to a rig that was rapidly maturing into something entirely his own.

Major rig change
Trey left behind the Mesa Boogie Mark III — his amp for the entire history of Phish to this point — in favour of a modular preamp/power amp setup. The CAE SE 3+ and Groove Tubes Dual 75 gave him a fundamentally different tonal palette, and three new rack effects expanded his texture options considerably.

Preamp New '95
Custom Audio Electronics SE 3+
Three fully independent preamp channels in a single rack unit, each voiced differently in gain structure and frequency response. Powered by seven 12AX7 tubes on DC-regulated heaters through a low-stray-field toroid transformer. An active tube post-EQ section provides up to 17dB of cut or boost in the punch and presence ranges, plus an 8dB output level trim — useful for compensating for the character of the paired power amp. Per-channel Bright switches grow more pronounced at lower gain settings, and all channels respond dynamically to guitar volume and picking attack. Channel 1 is the clean default; channels 2 and 3 are out of phase with each other and cannot be run simultaneously. Designed by Bob Bradshaw's Custom Audio Electronics in North Hollywood, CA — built from the ground up to drive line-level rack gear at +4dB.
Power Amp New '95
Groove Tubes Dual 75
A stereo rack power amp with two fully independent channels, each accepting a selectable power tube type: 6L6 (60W, hard and clean with a smooth breakup), EL34 (65W, compressed and raspy British character), 6550 (70W, tight and powerful, late to overdrive), or KT88 (75W, full-range with a softer, more musical overdrive). The driver/phase inverter tube is also swappable per channel — a 12AT7 for a cleaner, tighter response or a 12AX7 for a fatter, more gain-forward character. Each channel has independent Volume and Presence controls; impedance is selectable at 4, 8, or 16 ohms. Can run in true stereo or mono A/B mode. In Trey's rig, the Dual 75 received the output of the CAE SE 3+ and drove the two Languedoc-built 2×12 cabinets — completing the modular pre/power system that replaced the integrated Mesa Boogie.
Speaker Cabinets ×2 Unchanged
Custom Languedoc 2×12 ×2
Both Languedoc-built plywood cabinets continued in use, both loaded with Celestion Vintage 30s — now driven by the Groove Tubes Dual 75 power amp rather than the Mesa Boogie heads.
Tube selection — confirmed
Trey confirmed in Guitar Shop magazine (August 1996) that neither the Groove Tubes Dual 75 nor the CAE SE 3+ preamp ran new production tubes. Tech Steve Dikun sourced old new-in-the-box stock and loaded both units with them. Trey specifically called out old RCA tubes in the CAE 3-channel preamp: "I'm using this Bradshaw, 3-channel preamp now, and even that has old RCA tubes." The Dual 75 was similarly loaded with vintage old-stock tubes collected by Dikun. The precise tube types (6L6, EL34, 6550, KT88) remain unspecified in the article, but the use of NOS RCA stock is confirmed.
Debut uncertainty
It is not confirmed whether this new amp configuration debuted at the 5/16/95 Lowell Memorial Auditorium show or at the first show of the Summer 1995 tour on 6/7/95. No photos from either show have ever surfaced, leaving the exact debut date unresolved.
End of the Mesa Boogie era
The Mesa Boogie Mark III had been Trey's amp for the entire history of Phish up to this point — from the earliest Vermont basement shows through the full Bradshaw rack build of 1994. Moving to the CAE/Groove Tubes modular system in 1995 was the most significant tonal shift of his career to date.

Guitar
🎸
Unchanged through end of year
Trey's primary guitar remained the original Languedoc hollowbody — the MarMar — through all of 1995. The European curly maple top / padauk back-and-sides instrument with the mother-of-pearl Marley headstock inlay continued to be his main voice on stage.
Guitar Shop — August 1996
The August 1996 Guitar Shop cover feature provides the definitive published account of the MarMar's electronics and pickup configuration history. Full details are documented on the 1980s–1993 page.
Acoustic Guitar Use — 1995
Jun 7, 1995Boise State University Pavilion — debut of Acoustic Army, a song written specifically for acoustic guitar performance. This is the first appearance of a song composed for acoustic in Trey's setlists.
Fall 1995 tourI'm Blue, I'm Lonesome was performed acoustic at a large number of Fall 1995 shows — often along with Sweet Adeline and My Long Journey Home. The acoustic cluster pattern from 1994 continued, now anchored by this Bill Monroe cover.
Oct 3, 1995Seattle Center Arena — I'm Blue, I'm Lonesome performed acoustic. Video from this show also confirms the small percussion kit was present on stage — its first confirmed appearance on video. The kit was likely debuted the previous night (10/2/95, also Seattle Center Arena) but this has not been confirmed.
Oct 13, 1995Will Rogers Auditorium, Fort Worth — I'm Blue I'm Lonesome performed acoustic, along with Sweet Adeline.
Oct 25, 1995St. Paul Civic Center — My Long Journey Home and I'm Blue I'm Lonesome both performed acoustic.
Jun 20, 1995Blossom Music Center — the soundcheck's My Generation was performed acoustic.
I'm Blue, I'm Lonesome — acoustic anchor of Fall '95
The Bill Monroe / Hank Williams bluegrass standard became the most consistently acoustic song of 1995. Its presence in dozens of Fall tour setlists made acoustic guitar a reliable mid-show fixture throughout the run.
03
Rack System
🖥
The two-rack Bradshaw MIDI system from 1994 remained in place, but both racks saw changes. Rack A was trimmed — the Small Stone phaser and DOD 680 analog delay were removed. Rack B was significantly expanded, gaining the new amp system and three new effect units alongside the three Alesis Microverbs. Guitar Shop (August 1996) confirms four CAE 4×4 Audio Controllers total — two per rack — and identifies a Peavey Valverb as a fourth reverb unit alongside the three Alesis MicroVerbs, previously undocumented. The MTI Rotophaser sat physically on top of the first rack, surrounded by four microphones for quadraphonic feed.
New road case — Rack B
The custom wooden rack used in 1994 was replaced this year with a proper road case. Based on available evidence it appears to be a 16U case with 2" foam shock mounting — a significant upgrade in durability and road-worthiness for a rig that was now touring extensively. The manufacturer of the case is not yet confirmed.

New Effects — 1995
🎛
Rotary Speaker New '95
MTI Rotophaser
A "chopped Leslie" — essentially the top rotor section of a full Leslie speaker cabinet, designed specifically for guitar rigs. The Rotophaser gave Trey a genuine rotating speaker texture without the size and complexity of a full Leslie. Critically, the MTI Rotophaser has no built-in amplifier — it is a passive speaker cabinet only, requiring an external power amp to drive it. Controlled via a dedicated floor pedal with Mute, Speed, and Stop switches.
Tremolo New '95
CAE Super Tremolo
A rack-mounted tremolo unit from Custom Audio Electronics. The rate was controllable via a dedicated floor pedal, allowing Trey to dial in tremolo speed in real time from his pedalboard without reaching into the rack.
Univibe New '95
CAE Black Cat Vibe
Custom Audio Electronics' take on the classic Uni-Vibe effect — a phaser/chorus hybrid that simulates a rotating speaker in a different way to the Rotophaser. The Black Cat Vibe added a warmer, more organic modulation texture to Trey's palette alongside the MTI unit. Trey spoke highly of it in Guitar Shop (August 1996): "Bob Bradshaw recreated the UniVibe with quality parts, so it's not so noisy. It's silent and sounds great — I love that thing!"
Tube Spring Reverb New '95
Peavey Valverb
A 1U rackmount tube-driven Spring reverb unit — "Valverb" being a contraction of Valve and Verb. The Valverb uses a 12AX7 preamp tube to drive a genuine Spring reverb tank, producing warm, organic reverb character fundamentally different from the Alesis MicroVerbs' digital algorithms. Its addition to the 1995 rig makes perfect sense: the Mesa Boogie Mark III that Trey retired had a built-in Spring reverb tank he'd relied on for years. Switching to the CAE SE 3+ preamp — which has no onboard reverb — meant he lost that warm tube-Spring sound. The Peavey Valverb was the natural replacement, restoring a tube-based Spring reverb to the signal chain alongside the three digital MicroVerbs. Confirmed in the rig by Guitar Shop (August 1996).
Sampler Confirmed Fall '95
Roland MS-1 Digital Sampler
A compact rack-mount digital sampler visible in rack photographs published in Guitar Shop (August 1996). Those shots were taken at Bearsville Studios in Spring 1996 during the Billy Breathes recording sessions. We are confident the unit was in Trey's rack by Fall 1995 and remained through those sessions. The Roland MS-1 offered single-voice sampling with up to 32 seconds of sample time. Whether it was ever used live — and if so, how it was routed in the rig — has never been confirmed. It is absent from rack photographs taken during the Europe Summer 1996 tour, suggesting it was removed at some point before or during that run.
MTI Rotophaser — floor control
The Rotophaser was unique in Trey's rig for having its own dedicated multi-function floor pedal — separate from the CAE RS-10 MIDI controller — with three switches: Mute, Speed (slow/fast rotor toggle), and Stop. This gave Trey direct, real-time control over the rotary effect mid-song without relying on MIDI preset changes.
Rotophaser amplification — confirmed via rig diagram
The official Guitar Shop (August 1996) rig diagram confirms that the Groove Tubes Dual 75 has three speaker outputs, driving the left Languedoc 2×12 cabinet, the right Languedoc 2×12 cabinet, and the MTI Rotophaser ("Leslie") simultaneously. The article describes the Rotophaser as "the horn and crossover unit of a Leslie rotating speaker, which sits atop the first rack, surrounded by four microphones for quadraphonic feed to house or board."
This confirms that both Languedoc cabs and the Rotophaser were all powered by the single Dual 75 — consistent with the daisy-chain approach Trey had used in the early 1990s when a single Mesa Boogie output drove both Languedoc cabs. The three-output configuration is documented fact, not inference.

Floor layout note
The exact arrangement of floor pedals in this era is not fully documented. The most likely configuration adds the MTI Rotophaser control pedal and the tremolo rate pedal alongside the RS-10, volume pedal, and wah from 1994 — making this Trey's most complex floor setup to date.

Era Summary
◎
1995 is the year Trey's rig grew up. The Mesa Boogie Mark III — the amp that defined every Phish recording from the band's earliest days through the Bradshaw revolution of 1994 — was retired in favour of a modular CAE/Groove Tubes system that offered new tonal possibilities and greater flexibility.
The three new effects added in 1995 — the MTI Rotophaser, the CAE Super Tremolo, and the CAE Black Cat Vibe — pushed Trey's palette into territory it had never visited before. The Rotophaser in particular became a signature texture, its chopped-Leslie sound appearing throughout the year's most exploratory jams.
Meanwhile, Rack A was simplified — the Small Stone phaser and DOD 680 analog delay from 1994 were gone, leaving a leaner, more purposeful effects chain. The DM2000 and Tube Screamers remained as the core of the pre-amp signal path.
Late in the Fall Tour, a small percussion kit appeared on stage alongside Trey's rig for the first time. Based on available video evidence it was not present at the Shoreline show on 9/30/95, but is clearly visible in footage from Seattle Center Arena on 10/3/95 — the second night of that run. This points to the first show of the Seattle run, 10/2/95, as the most likely debut, though this has not been definitively confirmed.
The exact debut show for this configuration remains unresolved. No photos from the 5/16/95 Lowell show or the 6/7/95 Summer tour opener have ever surfaced, leaving open the question of exactly when Trey first plugged into the CAE SE 3+ on a Phish stage.

1995 is the year the Bradshaw rack reached full maturity — the Mesa Boogie was retired, the CAE SE 3+ and Groove Tubes debuted, and the Black Cat Vibe and Motion Sound Pro 3 arrived. Live Phish Vol. 1 (12/14/95 Binghamton) is the most celebrated single document of the era. The Halloween Quadrophenia show and NYE at MSG round out the year.
Research needed
The following items represent open questions for this era — areas where documentation is incomplete or evidence is not yet confirmed.
Small percussion kit — debut showVideo evidence confirms the percussion kit was present at Seattle Center Arena on 10/3/95 and was not visible at Shoreline on 9/30/95. The most likely debut is the night 1 Seattle show on 10/2/95, but this has not been confirmed. The exact kit configuration — what instruments it comprised — is also unconfirmed.
Acoustic guitar — make/modelThe specific acoustic guitar used throughout 1995 for mid-show acoustic appearances (I'm Blue I'm Lonesome, My Long Journey Home, Acoustic Army, etc.) has not been confirmed. Make, model, and year of the instrument are unknown.
MTI Rotophaser — exact debut showThe first show the MTI Rotophaser appeared in Trey's rig has not been pinpointed. It is placed as debuting in 1995 based on available evidence, but the precise date is unconfirmed.
Rotophaser — exact speaker impedance and load balancingGuitar Shop (August 1996) and its rig diagram confirm the Groove Tubes Dual 75 drove all three speaker loads — left Languedoc 2×12, right Languedoc 2×12, and the MTI Rotophaser — simultaneously off three speaker outputs. What remains unconfirmed is the exact impedance of each output tap used and precisely how the total speaker load was distributed across the amp's two channels.
CAE Black Cat Vibe — addition dateThe exact date the CAE Black Cat Vibe was added to the rig in 1995 has not been confirmed from available sources.
Rack A vs Rack B — unit placementThe precise distribution of units between Rack A and Rack B across the 1995 touring year has not been fully confirmed. Guitar Shop (August 1996) describes the rack layout as of mid-1996; whether it exactly matches the 1995 configuration has not been verified.
Roland MS-1 — live use unconfirmedThe Roland MS-1 Digital Sampler is confidently placed in Trey's rack by Fall 1995, visible in rack photographs taken at Bearsville Studios (Spring 1996, during the Billy Breathes sessions) and published in Guitar Shop (August 1996). Whether it was ever actually used live — and if so, how it was patched into the rig — has never been confirmed from available sources. It disappears from rack photos taken during the Europe Summer 1996 tour and its removal date is unknown. An open research question.
Peavey Valverb — exact debut showThe Peavey Valverb is confirmed in the rig by Guitar Shop (August 1996) and is placed as a 1995 addition based on Trey's switch to the CAE SE 3+ preamp, which has no built-in reverb — the Valverb's tube Spring reverb replaced the Spring tank in the retired Mesa Boogie Mark III. The exact show it first appeared has not been pinpointed.
