This vintage hardtail plate is modified for use with BIGSBY styled vibratos. 

This bridge is a great way to use a flat mount styled vibrato with humbucking or P90 pickups. For those of you building old style '72 Tele Deluxes and Thinlines should find this specialized bridge very useful when adding a Bigsby.

As you would expect from Callaham, these are fantastic quality.  The base plate is made from the same cold rolled steel as the Strat Tremolo Bridges and hand polished and carefully nickel plated to a mirror finish.  Really no other maker comes close to this.

Brass saddles are warm and mellow and stainless steel have more punch and sustain
