Hi
My 8 year old cort gb74 bass guitar has very recently started humming, The amp I use is a Fender Rumble 25 which is also 8 years old.
it sounds like electrical noise and does not go when I touch the strings or bridge (so I assume it is not a ground issue)
I can really accentuate the noise if I switch the pan pot to the rear MM Pickup and can make it disappear if I switch to front jazz pickup,
I have tried the amp from another plug socket but still the noise persists?
Any advice is gladly welcomed
Many thanks
Lucas
