I have a great sound coming from the Tube Zipper when my guitar volume
is maxed, but when I roll the volume back I loose my filtered sound. I tried
adjusting the sensitivity knob but that doesn’t work. I am trying to play
at a higher volume on my amp so it’s right at the breaking point of distortion,
and then use the guitar volume knob. All of my other pedals work nicely, but
the tube zipper doesn’t. I know that it is effected by the guitar input but is
there a way to make the tube zipper work?
Thank you
