Hello...I have searched the site and this is a widely discussed topic. I have a 2018 PRS SE Standard 24 and I love the tone (first PRS...not the last one guaranteed). I had SW put in a TUSQ nut installed after reading that there might be some tuning issues (on previous versions anyway). I now want to replace the stock tuners with locking tuners because tuning has been an issue. SW told me I would have to drill to use Grove 502c's (which they recommend), but I noticed on a thread in this forum someone mentioned Graph Tech Ratio Locking tuners because they come with InvisioMatch mounting plates. I know another locking tuners question, but I did not find the answer for my specific model so forgive me for starting yet another thread. I appreciate any suggestions you can provide me.
