Hey guys, I need your help again. It's obvious I'm not a tech wizard, but I'm learning more and more everyday, especially on this website. I think I've learned more in a month on this site, than I have in the last 6 months reading Bassplayer articles and articles from other internet sites. I'm having serious problems with my Carvin PB200-15 Combo amp. I think I may have killed it. One of the bands I'm in practices in a single screen movie theater before they open, so we're practicing in a theater that fits 250 people, with 25 foot ceilings, and it's carpeted. Needless to say, the acoustics suck and don't give me back any of my sound. Naively, I've been using my Carvin amp because I thought it had enough power. Well, I should also mention that my drummer, probably the best drummer I've ever played with, and seriously skilled, does have a problem with playing soft. The problem is, when I drive it too hard, it starts overdriving. (I think that's what's happening). I have the volume set between 4 and 5, the gain doesn't do a thing, nor does the compressor (I'm finding out that's a common problem with Carvins), and I've got the EQ set at 70% bass, 60% mid, and 85% treble. I've also got the bass knob at 4 and the treble at 8. I've pretty much turned the tweeter off cuz I think that's dead. When I really start playing hard it starts to overdrive, but it's mostly on the 4 - 9 frets on my E. What is going on? Is it the bass, the speaker, the frequency of those notes? Plus, I have very clearly realized that 160W Combo amp (which probably isn't even delivering that much wattage) isn't going to suffice. Thanks guys.
