Hi everybody,
After quite a long time, I’ve connected my English Muff’n to my pedalboard (wood, BTW). Unfortunately, when in Overdrive mode, it makes terrible buzz (in bypass mode – dead quiet). It’s not 50hz noise. I think it’s a ground loop, because when I wear my guitar and touch the pedal with my hand, the noise quietens.
But I couldn’t find any way to quieten it down. I’ve tried changing the power supply, and I tried connecting it alone (w/o the pedalboard) directly to my amp. I also tried different cables, with no effect at all. I’ve checked the tubes for microphonics – it’s not the problem. Whatever I do, there is terrible noise if I don’t touch the pedal, and it sounds good if I do touch it (if I play w/o touching the pedal, I get terrible crackling). However I can’t of course play and thouch the pedal at the same time!
Any advice would be welcome.
