I have a same problem. I use Ha3000 with GK 115T cabinet , and play Aria Precision(passive b.) copy (with DiMarzio pu from 70). When i play through the input 1(for passive) clipping start at 2 and distortion around 5. When i go through input 2 (for act.) clipping start at 4-5, and sound is clean, even on 10.
I'm from Serbia(Europe), and i can't call from here U.S.-service manager (lot of $$), so please contact me on mail, if you have an answer.
