Ive been taking lessons with TecDeth for almost a year now. Its worth the investment if your honest about wanting to get good at playing guitar. It requires you to practice. If your not practicing then youre not going to get better.
I tried to get PRS PTC to do a new fretboard install after covid and very recently. They wont touch that work order anymore. They at one point would do anything you were willing to pay for.
IIRC someone posted a PRS for sale that had body repairs done with shell inlay. It looked really good. I'm looking for those pics for reference, thanks.
