Brad, I have to tell you, and this is only from a basement test, but my 20 something yr. old 400RB actually sounds better with it. I'm not sure why. I know the two basically have the same pre, but that underpowered old dog sounds great through it while the 1001RBII sounds ehhh. The 1001 rocks with my Berg mini stack, but side by side with the UL-310 just so so to me. After playing around this afternoon, I'm taking the 400RB to the gig to try out the UL-310. Back to the original programing...... The LMII sounded quite nice with the UL310 on first listen. I don't own a T-Funk nor have I heard one per se', but knowing the T-Funk is based on the old AMP line, that was the first thing that came to mind when listening to the LMII. A bud of mine still uses his early 80's AMP rig, and it still sounds great to this day.
