Bought this for a headless project that never materialized. Looks like Steinberger specs: 0.706" pitch. 1.5" headpiece. Clamp-down headpiece accepts standard strings. Great inexpensive jump-off for a headless project. I actually have a vintage and very unique Ricken-clone short-scale (!) that I was going to use for this project if anyone is interested. Maybe I'll post that tomorrow. [DEL]$40 shipped ConUS! [/DEL] SOLD! Thanks for looking!
