Thanks guys. Those tips are pretty common knowledge around here. When I had mine and put it on a frequency analyzer, there was still a mid dip with the bass and treble turned down. Also, it kind of ruins the gritty sound a bit. I was thinking about getting one again, using the blend and maybe eqing the mids back in. You can do that with some gear like swr where this is a scoop going on but, with some stuff it just isn't possible. Im thinking the bddi is like this. I seem to remember using an eq pedal with boosted mids and the bddi was sucking it up like a black hole. Remember, I was using an analyzer so, I could see the dip.
