I'm using the effected line out and can barely crack the volume without peaking hte board (at least when I'm using my G&L). Even my passive MIM JazzV allows only about 1/4 volume before it peaks. What's going on? The other night, I hooked my qsc mx700 and the IOD to one of our yamaha 18" subs-- no problem, no peaking, no distortion. What gives? I could push the IOD to almost full volume and it sounded great (using the Jazz). At the last gig, I ran the G&L into the active input and the jazz into the passive side and was able to push the volume up significantly. Is there any good inexpensive solution? Thanx kids!
