I'm having problems with my Boss - Me 50 pedal. ive had it quite long and iv'e never had any issues with it until now. When i plug it in nothing happens but there is a really nasty sounding whirring noise? ive changed leads a couple of times but no different? Would it help if i bought a new lead?
Did you check your cables/which cable is connected to which spot. It could also be your guitar's pickups or jack on the guitar.
tried a new battery?
does your guitar work if you plug straight into the amp?
Could be fried, do you use batteries or a power supply?
