A nice gentleman walks into the shop with this SG and asks if I could plug the holes behind the bridge. He wants to give it to a family member as a gift after playing the guitar for years. The guitar was built with a different bridge and had at some point, probably in the 1980’s, been modified to a tune-matic bridge with a stop tailpiece. But alas, the existing bridge holes were not plugged and left exposed for all to see. There are a few tricks with this job. You have to match the grain direction of the mahogany as well as the color and finish without disrupting the original finish. If you can do that though you’ll have a happy customer for life.
