Wow! Thanks for the quick replies everyone. Of course I would love to have an awesome vintage tube amp, but I just blew the budget on the guitar itself so that's out of the cards for a while. Think "Caledonia Mission" by The Band off of Big Pink, or Robbie's tone as a whole on Last Waltz. Question though - I've read a lot about amps that "break up", what exactly does that mean, and how would I go about it? Gain all the way up? PS:
