My band rehearses at a rehearsal studio and every practice i find myself playing on a different bass rig - amp and cab combo. Usually they are pretty beat up. So i find myself spending a lot of time tweaking the gain and eq controls usually trying to get my bass to sound right. At home I find myself doing this a lot as well mainly because i can't seem to get my tone to sound like what i'd like it to. A good description of the tone that i'm trying to get is on the intro bass line to Nirvana's lounge act. Any suggestions of a quick way to tweak gain and eq settings to come close to this tone?
