on a couple of guitars i had got some post-nut resonance issue... palm muting on open strings sounded like someone was beating a bell with an iron mace...
my solution was very very simple... i put a small piece of foamy rubber (those things used under chair legs...) in the last two notches and vibrations were gone.
as long as some tone on open strings, of course...
does anyone know a better method (that doesn't necessairly involve changing the nut...)?
