I purchased a Darkglass X7 and have noticed if I have the low level set at anything over about the 2 o'clock position with the compression maxed it gives almost an octave effect and gives a weird overly distorted signal. This is with the the high level at any position and the volume can be at any level. It becomes worse however if I increase the volume on the pedal or high shelf. I thought that maybe I just got a back one since I saw an FAQ on Darkglass's website that addressed this issue. I bought another and it does the same. I'm curious if this is just the nature of the pedal or if I just received two units with issues?
