Bigsby B5 Vibrato with Full Callaham Upgrade

Excellent piece

Tone and sustain seem to be enhanced with the Callaham upgrade! It's nice to have a 360-degree arm too. I have mounted this Bigsby B5 on my new Gibson Theodore along with an ABM roller bridge and I am very pleased overall.

Needs to come with the newer lower power springs

This tremolo with all the upgrades is a piece of art! Thank you for the great product!
