I play a 335 through a Fender Pro, and I do both Jerrry and Bobby parts and usually in the same song! its a weird setup we have, since the other guy wont really do the chord inversions, so I end up taking them, and frankly have more fun with them than some of the Jerry parts. Usually, I will take the solos, and the bobby rhythm parts, but other times I do a conglomertion. I find that its not that difficult to switch, tonally, for the older 70s sound. I used try to cop the buzzy flange modern Bobby sounds, but now I just play straight with a little tap delay and a good chunk of Fender Reverb. I have a coil tap on my 335 so that helps me get more of a bite for solos and change it up on the fly.
I find that the Fender amps and their reverbs are very key to the sound. And a good chunk is in the hands, and how you choose your voicings. I am not like most on this board in that I am not interested in nailing the exact tone for each. I try to play fairly genuinely, but tonally, I feel I am close enough. I will post some samples. I do keep a tad more bass in there than Jerry would, just because I like it. While we do mostly dead, we do other stuff, so I want to have as much of me in there as I can.
