I own a Gretsch 5120 which I recently swapped the pickups out to install a pair of High Sensitivity Filtertrons. In order to do this, some minor modifications needed to be made.
First, I had to fill the screw holes made from the previous pickup bezels to accommodate the classic Gretsch bezels. I used toothpicks as dowels and (elmers) wood glued them into place. I placed the new pickups in more or less the same locations, and some of the new screw hole locations had some overlap. I dont think I can tighten the bezels down far enough because the holes dont feel as strong and that I am on the verge of stripping the new holes, but I need to do something because there is some buzz from the English mount ring risers that TV Jones sells for installing pickups into a 5120. I want to point out that the riser are a hard plastic and not a rubber, they have some flex but don't compress. Any suggestions as to how I should proceed? Is this something that I need to consider moving the pickups ever so slightly and use virgin surface for the screw holes to remedy?
Second, I recently had the guitar modified with an Earvana nut and also set up by a luthier who put 11-52 gauge strings on. I prefer 10-52, so I put those on after the install and while the guitar is intonated properly, it still doesnt sound in tune --the guitar seems to fluctuate in an out of tune as the strings vibrate, especially on the G string. The guitar played and sounded perfect after the luthier set up, so this happened after changing strings. The relief on the neck is fine and there is no buzz, but is this a string gauge issue? If so, I will just change back to the 11-52s until I can get it set up again.
Thanks a lot guys.
