Which guitars go with which tracks?

Ledbetter has a strat used on it. Mike talks about it, a lot. It's a '59. I'm assuming he uses that on Black and Alone, too (since they have the same tone).

Jeff uses a Hamer 12 string bass on Why Go, Jeremy, and Leash. Also, I think he uses that or an 8 string on Go.

Given To Wail have a pretty comprehensive list of gear used by the whole band, but they don't break it down to song by song/album by album. As far as guitars they used in the studio go, I don't really think you'd be able to get a detailed list together, as there's no official list like you used to get from bands like Metallica because of their endorsement deals. Plus, its really hard to tell the exact guitar right down to the model based on the track alone. You might hear a meaty rhythm tone and go "Humbuckers!" but that's not going to tell you if it's Les Paul Custom or a Les Paul Standard :P

The band themselves change their gear around a fair bit as well. Like last year when I saw PJ play Isle of Wight, Stone was using a Strat for Even Flow, which I'd never seen/heard of him doing before. That said, there's a lot of continuity on the live stuff. I think that they've tended to stick to the same(ish) gear that they used on the record when they first took new songs on the road, and then started trying the songs on different guitars as time has gone on. Track down videos of the songs you're interested in being played live during the specific era that they were released, and it should give you a good idea of at least the type of guitar, if not the specific model numbers etc.
