Callaham Front Roller Upgrade Kit For Bigsby B5 And B7 Units

All guitars equipped with a Bigsby B5, B7 and custom Fender B5 Vibratos suffer greatly from reduced frequency response and sustain because of the complete lack of quality of the front roller of the units. Our upgrade kits provides a solid, stainless steel front roller and axil that will widen the frequency response and sustain to where it should have always been. The roller is polished to a mirror finish and is grooved to maintain string alignment. This is a simple retrofit and pays huge dividends.
