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 won’t 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. Standard saddles have starter notches dead center, but optional saddles without notches are available. Models available for virtually any electric guitar! Choose the “Gibson® Guitars with ABR-1 Bridge” category to upgrade your ABR-1 equipped guitar (i.e., Gibson Historics and any guitars using ABR-1 style 6-32 threaded bridge posts), the “Gibson® Guitars with Nashville and Heritage with Schaller Bridge” category for a Nashville/Schaller bridge equipped guitar (requires optional Faber® bridge studs – pre made kits available!). Choose the “Epiphone & Other Imported Guitars” category for guitars with 4mm bridges posts (i.e., non-USA made guitars, such as Tokai), or, using the optional Faber® E-Sert or ESWKIT™, for many Epiphone, Tokai, Ibanez and other non-USA made guitars using a Large Bridge Post system.
