Hello guys,

A few days ago I bought a Boss FV-500H, and it works like a charm except for one VERY annoying thing: it starts to give off a horribly resonating sound whenever I play a G sharp (13th fret G) or any note closely surrounding it. When I keep pressing down on it with my foot I hear nothing, so it's definitely the pedal. Is there anyone who perhaps has something of a solution to fix this? Cheers!
