Hey guys I am brand new to PRS guitars although I have played for a few years. I just bought my first prs. It is a 2019 Mark Holcomb signature SE. I have heard that it is best to change the cheap nut that these come with and also the locking tuners. I wondered if anyone out there had advice and/or links to where you can buy the best upgraded parts for this guitar. I appreciate your time and thank you ahead of time for checking this out and responding. Take care!
