This may seem like a stupid question but when ive adjusted trimpots ive always disconnected the pedal from the powersupply and guitar leads, adjusted the pots and connected it all back up. Theres always something playing in the back of my mind saying I shouldnt be tweaking the internals when the pedals connected to the power supply. Is it ok to do it whilst the pedals connected up?
Your all laughing now arnt you!
