Happy Turkey day first of all, and I just wanted to follow up, I got my string retainer installed today and it definitely is an improvement. The A string was the only string I was having a problem with and this fixed it. It gives me a much better break angle off of the nut, which gives the A string a better tone, especially when played open. I was getting some vibrations before and this fixed it.
I have a couple questions though, should I lubricate the string retainer to prevent string breakage? I do this on my guitars, but is it necessary for the bass? If so what should I use? I use chapstick on my guitars.
Second question is, what would be the easiest way to fill in the hole left from the screw of the original string retainer?
