I removed a pedal which I thought was introducing some unwelcome noise.
Imagine my distress then when I plugged in at rehearsal to have my band mates recoil in horror at the racket coming from my amp.
Before I started playing that is.
I only hear a half of it as the upper end of my hearing is pretty shot away, but what I could hear wasn't good.
I had, in my naivety assumed that using battery power would eliminate such issues, but evidently there is more going on than I realised.
I am assuming that I need to strip it down and go through it lead by lead, pedal by pedal to find the culprit. I'm posting here for you to chip in with ideas, what to look out for how best to test it.
