Alright, I got the GK 1001 RBII. I HEARD great things about it, and I've been using it for about 4 months now BUT i haven't really been too impressed with it. I'm playing it through and ampeg 4 x 12 cab and I added a Sans Amp too. Any suggestions on how I should set this thing up? Or should I just sell it and get an all tube jobber?
