6/14 Edit- Added info about the bridge pickup changes in the Les Pauls.
Teppei has used many different guitars for live and recording, but recently has settled on these for live shows: his black 1985 Gibson Les Paul Custom, Blonde Nash T-Series Timewarp ('51 Telecaster/Broadcaster) and his Fender Jaguar Baritone. In the past, his black Les Paul was his main axe of choice (with his wine red 1977 Les Paul standard being used in the studio) but now it seems as if his Telecaster has become the most used.
The Les Paul is still used on songs like Deadbolt, Red Sky and Of Dust and Nations but the last couple of tours have seen the LP being used less. He used to string this LP with Ernie Ball 11-52s, but it is unknown if this remains true. Teppei replaced the stock bridge pickup with a Seymour Duncan. His studio Les Paul custom has a Dimarzio Super Distortion pickup in the bridge position.
The Telecaster has stepped up and become the main axe, and is used on Trust, The Artist In The Ambulance, Come All You Weary, Broken Lungs, For Miles, Hold Fast Hope, The Flags Of Dawn, Cold Cash and Colder Hearts and others. In an interview with Ultimate Guitar, he commented on his move toward his Telecaster with single coils for the more heavy material. This is uncommon in the rock world, and even in Thrice's past (the Les Paul was used much more on past tours). The Tele can still be driven hard, but leaves the articulation and clarity that is so key in the Thrice tone. As a little aside, this move toward Fender (he seems to be really liking his new '59 Fender Bassman reissue amp) really pleases me as I'm a Strat player who plans on buying an old silverface Twin Reverb and then becoming poor (and toneful) this Summer.
Teppei's baritone Fender Jaguar was used pretty much exclusively in recording the Fire EP, and naturally that is where it is used live. Its sound is naturally deep and heavy, but is another single coil guitar which again leaves more chime and clarity and is less boomy than a Les Paul or other humbucker-equipped guitar.
Teppei also keeps his P-90 equipped Epiphone Casino with him. This guitar doesn't seem to be getting as much use as the aforementioned guitars, but is still one which Teppei really likes due to the hollow body and natural tone of the P-90s. P-90 pickups are famous for being used in the early Gibson guitars, and were popular before humbuckers. They are single-coil pickups, but in a bigger package and have a bigger and warmer sound. This also causes a bit more noise, since they don't cancel noise like humbuckers and are stronger than single coils. The combination of the warm P-90s and the natural hollowbody tone is what keeps this guitar on the road. This guitar was played when I saw Thrice in February, but I can't remember when.
Stay tuned for a look at Dustin and Eddie's guitars too. If there's anyone out there reading this, feel free to comment with your comments, concerns, questions, ideas, gripes, etc.. I just set it to where there is no registering necessary to comment (just like on the Alchemy Index blog). Hopefully there's a few of you out there on the interwebs reading this stuff!
Edit 6/2- Thanks to Russell for pointing out some crucial things about Teppei's Nash Tele!
