Hi, I'm interested in using a Schaller GTM Nashville bridge on my Gibson Custom Shop Historic.

My historic has a Gibson no wire ABR-1 with ABR-1 posts that are mounted directly into the body.

The Schaller uses 4mm mounting holes and 4mm posts (that normally screw into a Nashville type threaded bushings). As ABR-1 posts are (I believe) 4 mm, I'm assuming this bridge would simply fit into the ABR-1 posts, just like an ABR-1 bridge. It would seem to me to be a direct fit - a straight drop in...

Am I correct or is there something I'm overlooking???

BTW I was intending to have the saddle adjustment screws pointing towards the tail-piece; as people often do with Nashville bridges. I just prefer them pointing that way.

Here is a link to the Schaller:

Like all bridges perhaps the key point is the spacing between posts. It should be easy with both guitar and bridge in hand to determine whether it will fit though.

Whenever monkeying with guitars, good measuring devices ar your best friend! A machinist' s rule like this or many others:

And a digital caliper that can be switched from fractional inches to decimal inches and metric, like the ones on this page:

Even the cheap $9.99 unit will work, but it sure is nice to have the fractional/decimal/metric conversion!

Just My $.02,
