Ok, I know existentially the answer is yes, but hear me out anyway. I auditioned for a band earlier this week and got the gig. They're a little off the beaten path. Two acoustic guitars, run through electric amps, and a not so hard hitting drummer. Since I didn't know what the loudness situation would be, I brought my main rig, a Markbass LMII and GK 115. It was total overkill. I'm thinking for my next rehearsal I'll bring my '77 Fender Musicmaster Bass amp. It seems like it would be loud enough with it's Eminence Texas Heat speaker. I'm of course afraid of blowing it up and/or destroying the speaker. The questions: Is 12 watts enough to compete with a medium hitting drummer and a couple of not deafeningly loud electrified acoustics? The Texas Heat (which is a guitar speaker) can handle my noodling at home. But is it up to the task? If not, which 12" bass speakers should I start looking into? I'm looking to avoid buying a rehearsal amp.
