Callaham Upgrade Kit, Bigsby String Shaft for B3, B5, B7

Makes string changing SO much easier - worth every penny and easy to install yourself

Great improvement in string-settling time. Will stay in tune in a matter of hours, not days (!!) like the standard "wrap around" Bigsby string mounting pegs.

Anyway, I'm glad Callaham took the trouble to do some real-world re-engineering work.

Thanks much - highly recommended

Put it on a B 12 and it fits perfectly on this model also, if the grover roller will fit im ordering one of those also, nicely built parts

Unlike the more modern Gretsches, the historic come with the old style Bigsby with the pins. And let’s face it, they’re a pain in the butt to restring. This Callaham shaft solves all that. Easy to install also. I’m using this on my ‘53 Gretsch Duo-Jet. Also, added a roller bridge that’s adjustable. Would definitely buy again if needed.

Fits perfectly and IMHO it is the best setup for your Bigsby
