I think your amp is just as important as your guitar. I have two amps, both Mesa/Boogies. One is a model called DC-5 and the other a DC-3. The DC-5 is really great, it has a brilliant yet very warm sound with lots of sustain. It's funny because when other guitarists see me with this amp knowing i play jazz, they always go "but that's a rock'n'roll amp!?!". For them a jazzguitarist equals Roland Jazzchorus or Fender Twin but seriously I've never played a better amp than the DC-5. I play a Ibanez AS-200 and a Godin nylonstringed electric-acoustic.
