Amplification: 2 Mesa Boogie Mark III Long Heads; 2 2×12 felt-covered cabs
Guitars: Sunburst Languedoc refurb. This guitar has Marley chasing a cat on the headstock with the “I’m the Mar-Mar” caption. This guitar initially appeared in the early 90s with a blonde top but was refurbished by Paul as a sunburst and appeared during Trey’s 2014 solo tour; Old Reliable as Backup (’87 Languedoc with the single coil slug).
Floor Pedals: Digitech Whammy II; Boss OC-2 Octave; TC Electronic Nova Repeater Digital Delay; Dunlop Wah; CAE Audio Switcher; Boomerang Phrase Sampler; Boss FS-5U (heavy things sample). There are several other tap-type switches, bypass switches, and an expression pedal here I haven’t seen before and can’t ID.
Rack Pedals: Shin-ei Univibe; Fulltone Tape Delay.
Rack: Furman Power Conditioner, the Korg DTR-2 Tuner, then a space split between the Alesis Microverb and the CAE Super Tremolo (the CAE Black Cat Vibe has been replaced by the Shin-Ei), then the Ibanez DM-2000.
Here’s a closeup of the refurbished Marley guitar. Trey used this on his solo tour in 2014, too.
Here you can see Old Reliable (the ’87 Languedoc) on the right in front of the horizontally-stacked, felt-covered 2x12s. 2 Mesa Mark III long heads sit behind Trey’s legs. You can also see the Boomerang logo from Trey’s Boomerang on in front of and below his left shin.
The CAE switcher is on the left. Below it is an unidentified expression pedal (more on that below. Note: a helpful commenter has identified this as the Meinl FX10 percussion pedal). To the right of that is the Whammy II, followed by the Wah, after which you can see the first green bit of the first TS-9 with the Ross Compressor sitting above it. Above that is the Boomerang with the logo taped over. To the left of the Boomerang is the TC Electronics Nova Repeater.
Above is a shot from 12-31-14 Theme From the Bottom with Trey working the Meinl FX10 pedal; accompanying the shot is the audio result Trey was achieving while working the pedal. It seems like he’s adding a woodblock-type percussion sound. He also has his reverse-Boomerang thing happening at the same time.
Above, a nice look at the Shin-Ei Univibe and Fulltone Tape Delay sitting on the rack. Accompanying the photo is a piece of audio from the 12-31-14 Theme with Trey employing the Tape Delay.
Above is a look at the rack and some pedals. The rack is in the process of evolving here; you have, from top, the Furman Power Conditioner, the Korg DTR-2 Tuner, then a space split between the Alesis Microverb and the CAE Super Tremolo (the CAE Black Cat Vibe has been replaced by the Shin-Ei), then the Ibanez DM-2000. On the floor, you can see the TC Electronic Nova Repeater rising above the rest of the rig, in addition to the CAE RS-10 Controller and some customized Boss FS-5U switches.
