The new TonePros® AVR-II (Advanced Vintage Replacement-II) is the upgrade for the old ABR-1 style bridge and is the "next step" in the evolution of high performance components retaining vintage appearance & functionality. While AVR-II's appearance is vintage, with the gaps above the intonation screws and the retaining wire, TonePros engineering has provided solid secure saddles with increased intonation travel. This prevents the old "loose-o-matic" saddle movement & "saddle lift" (the saddles are secure even if the wire is off!) while providing superior coupling for better resonance transfer.
This new design provides the solid intonation and increased sustain you expect from TonePros, along with the signature "Locking"TonePros features.
