Is it possible to bypass the 7-band Mesa 400+ equalizer and use a parametric or graphic equalizer (thinking a Rane PE17 or DEQ 60)? I have a hard time getting a "non-muddy" tone when playing with acoustic guitars (plugged into a small PA) and figured this might be a way to really shape my sound. If possible, how does it sound & how doe it work...where do I input from the EQ to the 400+. If not possible or this is madness, please let me know! Thanks for your help! KenO.
