I have the pedal version of the Rocktron Hush System. Mine has two different threshold settings that are footswitchable. I have one set up for minimal threshold and the other for larger noisegate. I usually leave it on the minimal setting for chording and rhythm work and kick in the other one for solo's as my fuzzes are quite noisy. Lately I have noticed that the minimal setting has been cutting notes shorter than usual and today it just completely cut notes right after I hit one. I konw there is a problem with the pedal. Does anyone know what the problem could be? Is anyone familiar with noisegate circuits?
