Does anyone out there know the threading on Yamaha agraffes? Or does anyone out there have a half dozen Yamaha bichord agraffes they would sell me? I'm modifying the low tenor scaling break in a GH1-B, and would prefer to replace the trichord agraffes with bichords without having to wait six months to get them from Yamaha. I know, I could use the originals and leave the center hole open (since that's what I'll be doing with the tuning pins), but I'd like a narrower unison. Then again, the existing trichord damper wedges may well work with the wide spacing without having to change them. In any case, I'd like information on the agraffes if anyone knows. Ron N
