http://www.faberusa.com You gotta check these out! Like I said in the clip, I used to think this was all smoke and mirrors, but it took only a second for me to feel, hear, and sense the difference. No joke! Instantly increased sustain and ringing chime...plus, the tailpiece and bridge are locked as well as the saddles. Check em' out...I'm planning to adapt all my Gibson and other stop tailpiece style guitars to these bridges. Available for import, metric, Nashville, and other measurements as well. Dig it!

Faber® Tone-Lock™ "Pro Sustainer System"™ parts are the best way to increase sustain on your guitar! Guaranteed!
Faber® Tone-Lock™
Our basic "Tone-Lock"™ is comprised of unique "vintage" STEEL studs and spacers, featuring our solid "No Gap" technology, and can be used with any standard sized stop tailpiece. Tone-Lock™ comes with 2 steel studs, in Imperial (inch) or metric thread, plus 3 pairs of spacers to place your tailpiece at your preferred height. Spacers can even be "stacked" for further customization and comfort. This is the best and most innovative tailpiece locking system available today and the best sustain enhancing product you can buy for your stop tailpiece equipped guitar.
Faber® Tone-Lock™ KIT
Enhance you guitar even further with our Tone-Lock™ KIT. The KIT includes our basic Tone-Lock™ studs and spacers and a Faber® TP-59 super lightweight aluminum tailpiece. As an added bonus, the price of the KIT is less than buying both items separately!
Faber® Tone-Lock™ Bridge
Our exclusive "No Gap" technology is also available in our Tone-Lock™ Bridge. Light years ahead of the usual "set screw" method of locking a bridge to the studs, one look at our system will show it's design superiority and how it actually can increase sustain. With our system, you wont damage your bridge post's threads - a common occurrence with the set screw method. The Tone-Lock™ Bridge, just like our non-locking ABR-59 bridges, features removable saddles. "Universal," in that lock nuts are provided in each kit for either 6-32 thread pattern (used on Gibson Tune-o-Matic equipped guitars prior to the introduction of the Nashville bridge, and currently on the "Historics") or 4mm, for use on many imported guitars and on the all Faber® replacement 4mm bridge studs (iNsert™, BSWKIT™, NSWKIT™ and E-Sert™). If your guitar has a Nashville bridge, or you have an Epiphone or other non USA made guitar using large bridge post inserts, Faber® bridge posts required to use the Tone-Lock™ Bridge may be purchased with the bridge at a 5% discount.
Faber® "Tone-Lock"™ MASTER KIT
All Pro Sustainer System™ parts can now be ordered in one convenient "Master Kit," at 5% discount over buying the parts separately. The "Tone-Lock"™ MASTER KIT includes "Tone-Lock"™ studs and spacers, a TP-59 tailpiece and a "Tone-Lock"™ Bridge. This is the kit to buy to completely upgrade your ABR-1 equipped guitar (i.e., Gibson Historics and any guitars using ABR-1 style 6-32 threaded bridge posts) or 4mm bridges posts (i.e., non-USA made imports, such as Tokai). Nashville equipped guitars will require the Faber® iNsert™, BSWKIT™ or NSWKIT™ to install the "Tone-Lock"™ Bridge included in this KIT. Most Epiphone and many other non USA made guitars using large body inserts for the bridge studs will require the Faber® E-Sert. When purchasing a MASTER KIT, you have the option of adding the required bridge studs, at 10% discount off the regular price of the studs.
