The BiggsFix Tuning Stabilizer Version 2 Dual Elevation Gold (BTS-V2-DE-G) fits Bigsby USA models B5, B7 and B12. If you want more options in your break angle, then adding the BTS-V2-DE-G 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 adding a little more tension than the original BricksBiggsFix - Perfect for Bigsbys mounted on Vibramate adapter plates.
Most USA made Bigsbys have an axle retaining set screw on the bottom of the Bigsby. This pesky little set screw requires a 5/64" Hex Key Wrench. If you need one, consider adding one to your order.
Also, consider adding a Super Squishy Spring to your order. While not increasing tuning stability, it WILL increase your playing pleasure!
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).
