This is for TL model guitars that fit 66mm from the string holes to the top screw of the bridge pickup (see attached diagram). The VT2ND is a revolutionary tremolo that can be installed using only the original bridge holes of a Telecaster body. Of course, you can reverse the process to return it to the original! Now, we've patented an all-new saddle design that works in three pairs but allows for independent adjustment of each of the six strings. This allows for precise, perfect intonation while delivering excellent tone across the entire guitar. There are two types of arms: one with the "VT" logo and one without. This comes with an arm without the VT logo. In addition to the main body and arm, the set comes with two plate fixing screws, a string height adjustment wrench (0.050 inch), and an octave adjustment wrench (5/64 inch). For installation, please refer to the "Installation Instructions Video" on this product page.
