ive been playing through this amp for a few years now. i got it when i started playing bass, and i was young and didnt know all that much about what i was buying. does anyone else use this amp? or have any opinions? i also played an ampeg 115 at guitar center with a stingray and it sounded great, very hard punch, very clear low end. do you think this amp is that much better than mine or could it be the stingray pickups compared to my fender jazz?
