The BiggsFix Tuning Stabilizer BTSV3 "Dual Elevation" fits Bigsby "licensed" models B50, B70 and B700. If you want more options in your break angle, then adding the BiggsFix "version 3- Dual Elevation" results in 2 choices of string angle to more closely match that of Bigsby's non-tension roller vibrato systems.
One set of holes matches the relief of the original BricksBiggsFix, while the other set of holes has 1.5mm less relief (a little more tension than the original BricksBiggsFix)
Telecaster is excluded from the list of guitars the stabilizer works with. There isn't quite enough tension left to hold the strings on the saddles when the stabilizer is installed without further modification (neck shim for example).
For our friends in Europe you will need a 9/64" hex key for installation. We have them available.
Also, consider adding a "Super Squishy" spring to your order. While not increasing tuning stability, it WILL increase your playing pleasure!
