Hi guys, I really need some help and advice. My Aphex Punch Factory used to work great. However just a while ago, I noticed that I had to really turn up both the volume and drive knobs to get a very minimal amount of volume coming through the amp. The knobs had to be turned almost to its end. And the light used to move around abit. Now when I play the DB meter has no light at all. And when i bypass the pedal the volume is very much louder than through the PF. Any ideas how to solve this?
