To those musicians on the list - I'm looking to spend about $500 or less on a guitar amp, and I want something that has some tube warmth as well as some flexibility. I'm a keyboardist who plays some rhythm guitar, I don't "shred", or solo at all for that matter - I just want something that can go from jangly clean to Raspberries/Badfinger style early 70s crunch. Any of you guitarists out there have anything to say about the new Vox modeling amps with the tube pre-amps?
