I had some time today and was able to remove the strings, polish the frets, oil the fretboard and bridge, clean it up, and put on some fresh strings. The action was good but ideally I would want it a tiny bit lower. However, it was playing good and I didn’t want to lower the saddle until I spent a lot more time with it and felt it was necessary. I removed the saddle while I was cleaning it and noticed something in the saddle slot of the bridge. There were two really thin cardboard shims under the saddle. Those can’t help the sound transmission! I removed them and strung it up. The action is now exactly where I like it with plenty of saddle still left. That was a good reminder to myself of why I take off the strings, clean and inspect everything on every used guitar I purchase.
It sounded good before but now it sounds great. Much louder and when you pluck a note is just keeps ringing and ringing. I can’t wait until the strings settle in a little to see how it sounds!
