Amplification: Mesa Boogie Mark III Long Head; 2 2×12 felt-covered, vertically-stacked cabs.
Guitars: Trey used Old Reliable (’87 Languedoc) for these shows, but had backups (See photos).
Floor Pedals: Digitech Whammy II; Dunlop/Teese Wah; CAE RS-10 Audio Switcher; Boomerang Phrase Sampler, Teleprompter control, Boss OC-2. There are also several other customized pedals that I can’t identify.
Rack Pedals: Shin-Ei Univibe; 2 x TS-9, H&K Tube Factor, Tru-Tron3x
This shot covers almost everything. On the rack behind Trey you can see the two green TS-9 pedals. Counter-clockwise from there you see the H&K Tubeman, the Uni-Vibe, and then the Tru-Tron3x, all of which are presumably being controlled by the CAE. This is the first time that the Tru-Tron appears in Trey’s rig (Garcia was, of course, one of the most famous players of the original Mu-Tron) and the first time that Trey places his Tubescreamers on the rack behind him. It is also the first appearance of the H&K.
On the floor, you can see, from right, the Boomerang, CAE, Wah, and Whammy. The three-piece pedal on the extreme left, which also showed up in Atlantic City for Halloween, is a controller for Trey’s Teleprompter. You can see the edge of the prompter screen in between Trey’s two monitors. You can also see Trey tapping these pedals to scroll through the monitor here. It makes sense for this to appear during shows where Trey is dealing with a bunch of new lyrics.
Behind Trey and below the rack is the Mark III long head. Note: no Analogman Sunface logos visible on the TS-9 Tube Screamers, which is consistent with Summer 2015. To the right of the head/rack are the two 2x12s. It appears as if only one speaker of the four is (double) mic’d, and one is covered up.
Another look at the amp, guitar (and backups), speakers, and rack rig. This is the first time we see the rack in the incarnation it would settle in to at least through Summer 2016, including, from top, the Furman Power Conditioner, Korg DTR-2 Tuner, Ibanez DM-2000, and TC Electronic D-Two.
The guitar on the right is “Old Reliable,” the original 1987 Languedoc with the “Who’s the Mar-Mar?” inlay on the headstock. In February 2015, Tom Marshall tweeted that Trey had just put the single coil pickup back in the middle position in this guitar. I assume this was to get some of the twangier Garcia sounds for this show.
The guitar all the way on the left is the second Koa guitar that Paul built for Trey in 1999. The guitar in the middle is the 1996 Koa. At the 6-22-16 Minneapolis show, Trey said he mostly played the ’96 Koa through Big Cypress and that “it was over this last break, I hadn’t played this in years, and I took it out and it was like holding on to an old friend.” It’s unclear what break he’s referring to, but the 1996 Koa was Trey’s primary axe for Summer tour 2015. It’s easily distinguishable from the 1999 Koa, which has a much more prominent flame and the unique “bracket” inlays at 12 and 24. The 1996 guitar has parallelogram inlays at 3, 5, 7, and 9 and larger parallelograms at 12 and 24.
