Only Callaham could and would make this, machined from a block of aluminium and polished to perfection this is the final part for your bigsby upgrade

This is a precision machined arm bracket that allows for full 360 rotation for the vibrato arm. This allows a player to position his picking hand without limit and maintain control of the vibrato.

Fits the following Bigbsy models: B3, B5, B6, B7, B11, B12 and finally B16. 

Note: Not for licensed or import bigsby styled vibratos ***Please check the exact model of Bigsby on your guitar on the Guitar Brand website or contact them***

If the spec says B50 or B70 or anything other than the exact list above these parts will not fit.  The extrs "0" denotes it is a licensed unit.
