I'm really trying to like this pedal, but lately it's been vexing me. I bought it because the sound was supposed to be pretty close to a Mu-Tron III. It does the nasal BWAPPP thing pretty well, but for whatever reason, regardless of what settings I have it on and how hard I play, it always seems to want to act as a low-pass filter first, and it's like one has to shove it to get it to do the Bootsy thing. Right now I have it at sensitivity 10, peak about 8, bandpass mode, drive up, low range. This works for BWAPPP but it seems to be erratic, and very sensitive to minor changes in the strength of the incoming signal. If I have the sensitivity at anything less than 10, I either get dub or no effect. Has anyone else run into the same sort of issues?
