[quote name='7string' post='694559' date='Dec 27 2009, 10:04 PM']Have you changed guage or make of string since you glued the nut on? Do you have any buzzing on the lower frets? I know this sounds silly but is the nut the same way around as it was before?
A new nut isn't a complicated job, but it takes time and needs accuracy. If you're not confident with files and sanding then a tech will be able to do it for you. Go for a bone nut if you can.[/quote]
When the nut fell off I took it to a guitar tech. He put the nut back on and new strings and I noticed he'd done some filing in the grooves on the nut. There is no buzzing apart from on 4th fret d string. I suppose only certain gauge strings will fit into the grooves on the nut because the ones i've got on at the moment go on fine but the ones I recently tried just would not fit into the grooves. I've never had problems with different string gauges on other basses!
