Heres my situation. I have a GK 700 RB(old one) and an avatar B210H and avatar B115. Both are 8 ohms. The GK puts out 350 watts at 4 ohms. The B115 is rated for 600 watts rms and the B210 is rated for 350 watts per speaker. Unfortunately, when i bought the two, i didnt know anything about speakers and amps and how underpowering a speaker can be bad. Basically, now with my band, i have to really crank up the volume to be heard over the two guitarists. Im losing all of my headroom and my bass is sounding like crap because im clipping my amp. Not to mention, my GK seems to be having that solder problem that everyone keeps talking about where the volume cuts out and sound gets distorted. So im looking for a new head. My budget is around 800-900 dollars and i know i wont be able to power my cabs correctly with any head in that price range but id like to get something that would power my cabs better and with less need to crank the volume to be heard. Im up to try anything, SS preamp or tube amp, im just looking for ideas at this point. thanks!
