Thanks guys!
Sounds good. Now I just have to figure out if I really need one, or if I'm just being GASsy. :D
The guitar doesn't stay in tune that well, and I'm pretty sure the bridge is the culprit. I doubt it's the nut, because that's got half a ton of graphite in it. And it ain't the string retainer, because I don't use it!
The strings are returning to pitch sharp, which Trevor Wilkinson says his bridge will fix.
