I have a OM style guitar and I run it into a Boss AD-8 acoustic processor. I have it really bassy cause i don't like thin sounding acoustics, how can i avoid feedback problems? I have a feedback buster in, and the eq is high on the bass end and low on the treble end, and low on the mid end, and it still feeds back sometime. Should i introduce some more mids? I just want to avoid a thin sound and feedback. Any suggestions to help me out?
