I have been trying to tweak the compressor on my me-6b to a usable setting and I found that it is only usable with the attack at 0, otherwise, every note is followed by a smooth pop, it sounds like a pillow is hitting every note. Otherwise, the compression is nice with the sustain at about 10 out of 15, but it is way too noisy. I still get a little pop when I play hard with attack on 0. This has been the only negative of this pedal. Any explanation for this?
