Long time six-string guitarist and limited experience on bass. I recently purchased a Fender Rumble 200 (15" speaker) and a Sterling Stingray Sub HH. I exchanged the Sub for a G&L Tribute JB2 which I like much more so far. Between the bass and amp this is the biggest purchase ($900) I've made on gear in decades. I've read a lot of positive reviews about both which help influence my decision. However, I only tried out two Rumble's at GC and no other amps. I found the humbuckers on the Sub to be muddy and dull. The bridge quality seemed suspect and the pickup selector was very noisy/scratchy. The build quality of the G&L looks and feels much better than the Sub. Only complaint I have about it is it's very bright tone. Rolling of the volume and tone a bit seems to get it closer to a traditional JB tone. Anyway, what do you think? Money well spent or are there better options?
