I recently purchased a 1974 M-75CS. Tobacco finish. Very, very nice in all respects, except that both E strings have begun to buzz when open. Fretted there is no buzz. The other strings are fine with no issues at all. My thinking is that the nut slots are worn too deep and that either a shim or a new nut is in order. If anyone has had experience or has any advice about this problem or with nut shims or replacements on your Guild electric, I would be most appreciative to receive your feedback. Thanks,
