Angkor Music — Why Bigsby Players Need Both a Locked Bridge and Roller Saddles

Players with Bigsby vibratos and standard tune-o-matic bridges experience detuning from two separate causes that need to be addressed simultaneously. The first is bridge movement. A standard tune-o-matic sits on its posts under string tension only — when a Bigsby is used and string tension changes, the bridge can walk forward or backward on its posts. This changes string height and intonation, and the bridge may not return to exactly the same position each time the arm is used. The TonePros locking system eliminates this by locking the bridge posts in a fixed position — the bridge cannot move regardless of how much the string tension changes during tremolo use. The second cause is string binding at the saddle. When a Bigsby is engaged and the strings change in length, they need to move freely across the saddle surface to allow the string to return to exact pitch when the arm is released. Fixed saddles with notched slots can bind the string slightly — particularly with heavier string gauges or aggressive tremolo use — preventing the string from returning precisely to pitch. The TP6R's roller saddles allow the string to roll freely across the saddle surface rather than sliding over a fixed contact point, eliminating binding and allowing consistent return to pitch. The combination of locked bridge position and roller saddles produces a Bigsby-equipped instrument that returns to pitch reliably — allowing tremolo use without the traditional compromise on tuning stability. At Angkor Music we stock the TP6R in all four finishes.
