Faber® guitar parts are truly "State of the pArt!" They were designed to meet the demands of guitarists who want to get the most out of their guitars, in both convenience and, more importantly, in tone. In addition, Faber® guitar parts address the shortcomings of existing products on the market. For example, the leading tailpiece locking studs do little more than just lock the tailpiece to original style studs. They claim more sustain, but look at the design and think about it. Is that system doing any more than what the strings do naturally under tension? Not at all! On the other hand, look at the Faber® Tone-Lock™. Examine the exclusive and innovative "No Gap" technology and you will realize that this system not only locks the tailpiece, but also provides complete and solid contact from the top of the tailpiece stud all the way to the body. The result is an actual, noticeable, real increase in sustain. The effect is virtually the same as having the tailpiece all the way down on the body, which is impossible on most guitars without "top wrapping," because of the steep angle and the problem of the strings touching the back of the bridge. With Tone-Lock™ you get the best of both worlds! This same kind of innovation and thinking can be found in all Faber products.
