After connecting the mics to my amp I´m afraid I have to send both mics back, it´s simply not usable (for me, on my bass). I have to engage the low cut, cut the highs, can dial out the first feedback frequency, but still there are some weird resonance things going on. With a lot of filtering this can get loud with a balance sound, in front of an amp, but for me and I guess for most of us this is to complicated and fuzzy for live use.
