I restored a 1925 Martin 0-18K. Everything was saved as original and fully restored right down to the French polish, even after being left in an attic in Arizona for years (total meltdown, warped and cracks). I put way more into it than it is worth because I want to play it and it does sound wonderful. It came out looking like new except for the frets and fingerboard.
However, the frets were marginal and as such the saddle/bridge is too low. Also, I will eventually wear them down to nothing. Where can I get the tangless rectangular (cross section) frets so I can keep it original?
BTW, Frank...I saw your refret job using rectangular frets but I didn't see a material source referenced. I have searched the internet, called suppliers and even Martin. No one even seems to know what kind of frets I am referring to.
Thanks,
Dave
