I've taken the basic mesaurements from my very accurate repro Modern Space Trem Claw, and after using it on my guitar, made some tweaks of my own.
It's not as vintage accurate in terms of specs but, for those who arent too bothered about that, I think it plays well. Most of the changes were done merely for my own personal tastes.
The biggest changes worth noting are:
- Chamfers to the holes where your string ends with sit - this allows the string to sit a little lower for a better break angle
- Enlarged mounting holes. My hope here is that as the mounting holes tend to be a little off on some of the various types of Hagstrom-style Trem units, this will allow for easier mounting without needing to file the holes at all. I cannot guarntnee anything obviously, but if you are worried that your measurements don't line up exactly with what I listed in the Original Trem Claw, this might be better for you.
The original trem claw can be found here: Modern Spaced Hagstrom Tremolo Claw
This claw can either be used with vintage Hagstrom-style Tremolos to get modern string spacing, or mounted direct to the body for a unique stoptail piece.
I can't guarantee this will work with all Hagstrom-style Tremolos being that I know a few different kinds of Hagstrom Trems were made, but this seems to be the standard one in my experience. If you measure the 3 mounting holes and they are about 6.3mm in from the back of the plate, but more importantly, the two outside holes are 16mm from the centre hole, then this should work for you
