Topic: String Buzz
This repair might be of interest to some of you.
I had a guitar brought into the shop with several strings buzzing. The neck was straight and the bridge was rather high but on further inspection I found that someone had been lowering the action by filing down the nut - and going too far. I was struggling to find a replacement that would fit but then decided on another plan of action.
I have always been an advocate of guitars with a zero fret as they always have a low action. So I took a piece of fret wire which is a 'T' in profile and I filed of half of the top bar to make it an inverted 'L' shape. I removed the nut and fitted the modified fret between the fretboard and the nut like so:
After lowering the bridge the action all along the fretbord was great and the customer was happy.
