Can anyone tell me any info about the new acoustic B810 cabs. I currently have the goldline gk cabs, 410 and 115, powered by an ampeg svp preamp through a qsc gx3 power amp. I've been running it in crossover mode, but the tone is a bit harsh for me still. I play a fender 75 reissue, which I love. The new Acoustic B810 is roughly the same price range as the GK. If I had the dough, I would spring for the Ampeg 810, but at GC I can trade my cabs in and get the acoustic at a fair price. Any suggestions?
