So, after all the discussion here about the merits of bone pins and saddle, I decided to fit them to my 000-28EC.
I bought the pins - 2A, and bone blanks from Stew-Mac. Using an online radius gauge, Dremel multi-tool, and a sharp pencil
I cut my own saddle. The bridge pins do stand proud somewhat, as I was told they would - normal for Martin!
So, was it worth the effort and cost? Absolutely it was! It has improved tone, volume, and overall sound without doubt.
I am now going to do the same with my 45s.
