Hi everyone, quick question for you all. I just picked up an '81 Peavy T-40. Got it for a great deal with the original fitted case. Anyways, I am getting buzz on fretted notes, mostly on the E string. The weird thing is that I think the buzzing is coming from the headstock side of the fretted note. I am guessing something needs to be adjusted. What should I look for? The nut is metal. Should I replace it? I am using D'Addario Flex Steels, if that matters. I usually use Chromes. I have never noticed this issue on any other bass. The T-40 can be adjusted at the neck, bridge and the back neck plate. My action is pretty high at the moment and I'd like to lower it but I want to figure out the buzz first. Any ideas? Thanks!
