wasup fellas, after reading Kernpre's thread on the DB680, i've been tooling around a bit more with my DB680 parametric, too. usually, i'm just boosting the low mids, and leaving the high mids alone. but i'm starting to realize i dunno how to cut frequencies. do you turn down the cut knob and just spin the freq. knob, until things clear up, or are there particular frequencies i should take note of? any pointers? other than the DB680, how are y'all using your parametric EQ'ed pre's?
