For those who do not know what I mean, when I say DIY shows, it usually refers to shows played in houses, basements, and the occasionally DIY venue (just some rented space, nothing acoustically special about it.) These shows are not mic'd (besides the vocalist) In my experience, especially in bigger rooms, nothing besides a big rig or a powerful tube amp will really do the job. For awhile, I was using two combo amps (one had a preamp out) just to get loud enough, but I kept blowing speakers (it took like three blown speakers to learn my lesson.) My last diy gig I used a b600h on a hartke vx 215, but that head really can't drive two 15's, so now I use it on a b810 cab, which is almost too much! Anyone else have some exp in DIY/ punk shows? I'd like to hear about it.
