Hi i recently built a 5 knob compressor and tried messing with the trim pot and used an 18 volt power adapter as recommended. My bypass signal is pure, but when i engage the effect the signal becomes very distorted in a synth fuzz sounding way. Also the led sometimes flickers very dimly on when in bypass mode and when engaged it sometimes flickers between dim and normal brightness. I hear static when the led flickers. I inspected the layout pretty intensively but found no issues. I even use liquid black tape on the backs of the pots and enclosure plate to ensure that the signal would ground at at these common problem areas.....Any ideas as to what could be going on?

Thank you for your time,

John

You may want to check your joints on your power adapter wiring.

It sounds like a short somewhere. You should check for bad solder joints and reflow any suspect joints.

Also, be sure to check your component placement to be sure you don't have a couple mixed up.

Pics are always helpful if you have them.
