ok so I am looking for a new bass rig. nothing huge. Bass is my secondary instrument at college,( voice being my main) There is no need for loud bass playing there but with my other band I need more volume....blah blah blah thats pointless talk.. My question is... Should I get a power amp and by a separate equalizer?? like go completely rack mounted system.. Or should I just get a regular amp... do you guys know what I'm talking about?.. I am going to be putting an ampeg 4x10 or 4x12 cab underneath it.... thanks
