Hi guys! I need help deciding on a bass amp.. I'm using a fender rumble 15w at the moment, with a TBC AP-500M bass (which i love! ) But I want to upgrade to something bigger and better. I play mostly slap, really, and I want to spend somewhere in the area of 600-700 AUD on a new bass amp. Would I be better off getting a combo or a stack (if i can even get one for that price, i'd love a stack though ) I don't really play outside my room, but I want something that sounds better than this.. Any ideas? personal experiences? Thanks!
