The BiggsFix Tuning Stabilizer BTSV3 fits Bigsby "licensed" models B50, B70 and B700. If you are experiencing too much down pressure and your string angle over the bridge is extreme, then adding the BiggsFix "version 3" results in your string angle more closely matching that of Bigsby's non-tension roller vibrato systems.
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.
For our friends in Europe you will need a 9/64" hex key for installation. We have them available here.
Also, consider adding a "Super Squishy" spring to your order. While not increasing tuning stability, it WILL increase your playing pleasure!
