Amps
Marshalls! Any way I can get them!

FX
SansAmp GT2 -- I'm a lazy person who doesn't like actually carrying the Marshalls
Digitech Multi Chorus
Digitech DigiDelay
Ibanez Tube Screamer

I've got other FX, but these are the main ones I use. Every now and then I'll use a volume pedal live, but at the moment I can't find the dang thing.

I've found that just plugging an acoustic guitar straight into a board doesn't give me the sound I'm looking for, so even when I play acoustic I run it through the SansAmp or the Marshall to give it a bit of tube warmth. The Tube Screamer lets me put a little bit of distortion on a song when I want it.
