Mesa Boogie Triaxis Guitar Preamp

From a November 2011 article found on mesaboogie.com: "The core of the preamp switching and FX integration happens via Mesa/Boogie Amp Switchers controlled with Digital Music Corp.’s GCX Expander switching units. The Boogie amps being switched are two Triaxis Preamp’s run into a 2:90 Power amp. One Triaxis is set to the Mark IIC+ mode while the second Triaxis is used for clean sounds in the Green Clean mode. Like Kirk, James also has DBX Quad gates and T.C. Electronic G Major FX Processors along with a few extra pedals kept in the rack. The signal runs out of the 2:90 into two Mesa Traditional Straight 4x12s for a true stereo mix." (original source: http://mesaboogie.com/news/2011/11/metallica-live-rigs/)

In this video, John Petrucci's guitar tech, Maddi Schieferstein, gives a rundown of the guitar rig that was used during Dream Theater's 2014 "Along for the Ride" tour. The Mesa Boogie Triaxis can be seen at 0:23.

You can see it here in his rack. Later, he replaced the Triple rec with it.

"For the solo CD and first 2 SymX CDs - the only amps I had, at that time, were a Marshall JCM800, Fender M-80, a Mesa/Boogie recording pre-amp. By the third CD ( Divine Wings ), I had bought the Tri-Axis and for some of the solos, I used a Rockman Compressor/Sustainer as a preamp ( in front of the Marshall...if I remember correctly ) - but only on that CD - thus - the 'Rockman-esque' tone on some of those solos. I always like to experiment and try out new things - different pre-amps, cabs , mic placement, etc."

While recording 2 A.M. Wakeup Call, Vrenna used some virtual synths, lots of outboard synths, live drums, a live acoustic guitar, a six-string Taylor and a nylon string guitar, plus he borrowed a couple of 12-strings from some friends for a couple parts. There is a lot of live bass on the record as well. "We used a five-string Fender jazz deluxe, which is a really good-sounding solid instrument, and it was all recorded through the Line 6 Bass Pod," says Vrenna. “We did some direct stuff with the guitar, but we used the Mesa Boogie Triaxis. That one is pretty awesome for direct I/O".

The user of the UltimateMetal Forum saw Type O Negative live in 2008 and wrote down the whole setup he saw that Kenny Hickey used. > He had the Rectifier on top most likely as a backup, as it wasn't turned on the entire show. In the rack he had: TC Electronic G Force Mesa Triaxis Mesa 2:90

In [this archived version of a December 2000 article from *Sound On Sound*](https://web.archive.org/web/20150606082550/http://www.soundonsound.com/sos/dec00/articles/underworld.asp), Underworld bandmate Rick Smith explains Karl's then-current rig. "Hyde's live rack is very complex, according to Smith, partly because the guitarist/singer has several input sources to choose from: vocal mic, guitar, vocoder, Mesa Boogie Triaxis guitar preamp, CD player, and Akai MPC2000."

According to this page this is one of the amplifiers he uses.

"The direct signal of [the Axe-FX] goes into his ears, and then it goes into the Boogie 2:One Hundred and that feeds one set of speakers. And the other side gets split off into the Triaxis. So we're blending the Fractal amp modeling with the real Boogies," says Mike Derks guitar tech, at 17:50 in this rig rundown video, by Premier Guitar.

According to his official website, this is one of his amps.

"For "Parallels" we used Mesa Boogie amps. I had a rack the size of a refrigerator! Jackson made me custom guitars. I ran those through a Boogie Triaxis through a 395 power amp. A couple of ART multi-effects units, noise gate, MP1 harmonizers, parametric eq’s, and an Abacus midi controller. That set-up, but with a smaller rack, was used for Inside Out as well." Frank Aresti

Mesa/Boogie Triaxis Preamp, 20/20 power amp, Thiele 1x12 (x2). Tone for days, extreme headroom. Fantastic stereo Boogie rig, all midi, ran in conjunction with a Marshall JMP-1 midi preamp into two 1912 1x12 cabinets. Some Alesis and Digitech midi units, as well, all operated with a Midi Mouse pedal. Went this route sometime in the '90s, subsequently used for most It's OK! and Redd Kross gigs up until 2015. A bit more manageable in the size and weight category. My last run with a live tube rig; the gradual degradation of tone, and the cost and time of maintenance, led me to retire all of my tube amps from the stage, and just keep them for the recording milieu.
