Has anyone come across R-09 preamp being deffective causing bass distortion on recordings? I have been running DSM mics with the bbox Mic-in, plug in power OFF, level meter not going over the -20db mark even at very loud rock shows. The bass sounds distorted on most recordings I've made since summer this year. What's interesting is that the more bass roll-off frequency I set, the more distorted bass I get. Is this possible at all?
Any insight would be highly appreciated.
