Callaham American Std Premium Upgrade 2008 Model & Later

This is an upgrade that is a direct replacement on American Standard Guitars that are made in 2008 or later. The Vintage style "CG" saddles are 2 1/16 spaced bridges and the height adjustment screws are 1/4 length for the E's and 5/16 length for the others.

When the vibrato bridge was first designed in 1954, it had a machined steel inertia block for the simple reason it gave the instrument the required sustain and harmonic content. Over the years, manufacturers have continuously made this part more inferior in order to cut costs. We manufacture an exact replacement block for stripped original bridges and it can be retrofitted onto any reissue instrument giving a dramatic increase in both sustain and frequency response. 

Every bridge is hand checked for arm fit and smoothness.
