Bigsby, a division of Fender/Gretsch, is reintroducing the aluminum neck shim designed by Paul Bigsby for use with the Bigsby B16 vibrato, which is specifically designed for use on the Telecaster. Though the shim is not required for use with the B16, it adds height (3/16”) and pitch angle for the neck, and many suggest adds sustain and high-end response to the tone.
