I dont know much about amps, but i need one and can only afford to spend around 600. I want a seperate head and cab. The kind of sound im lookin for is a high end, trebley, punchy sound, (Green Day's Mike Dirnt bass sound is probably the most common band i can think of that would be similar..also Matt Freeman from Rancid) ive heard trace elliot handle this pretty well..? I'll be using it for gig'n/touring etc. If anyone's selling an amp, has any good webstore links or advice at all it be much appreciated! Thanks a lot Steve
