I have a spector rex2000 which is a great bass ,however recently the bridge pick-up seems to be emminating a sort of high frequency hum when switched on.I have insulated the electrics cavity but to no avail its just low frequency humming now,it only goes away when i touch the strings and the neck pick up is fine on its own.It is really getting on my nerves
could someone point me in the right direction to fix this pleeeeaaaasssee!
i solved the problem the pick up was faulty got a new emg in now and problems were sorted
pick-up earth problem.
