I recently picked up an MMA6000, are the knobs on anyone else's kind of off? They never line up with the markers on the preamp and they both kind of stop in the middle of the lines so it makes it hard to tell if I've got one channel set higher than the other. After thinking it over, it's near impossible to see their large line on the knob in low light, so I'll probably buy some bright colored dot stickers at office depot and make my own pointer line. Just wondered if anyone else ran into this problem, although if my recorder had stereo levels there'd be no issue.
