I know I should have stayed solely acoustic, but the time had come. Acoustic guitarist for five years recently turned bass player (picked up a Godin A4 cheap and like it a lot) but I know nothing--not next to nothing-- about amps. I don't need anything super huge or beefy as I'm only going to be playing with a few friends. Something hopefully less than $400...and can't be more than a single 12" due to space limitations. I don't want some wimpy practice amp; I'd rather have something that I wouldn't outgrow in a year. I've played a Hartke (don't remember the model) and it was nice, also played an Ampeg (don't remember the model) and it was also very nice. I was just wondering if anyone had any suggestions as to what to look for. Thanks!!! BTW I play all sorts of stuff from bluegrass to metal...but prefer to stay on the lighter/jazzier side of things.
