The TonePros T3BT is a locking Nashville style bridge with ''easy to use'' features like intonation adjustment on the pickup side, phillips head saddle adjustment screws
The TonePros T3BP has many improvements over standard Nashville bridges including intonation adjustment on the pickup side, phillips head saddle adjustment screws, and pre-notched saddles for quick installation.
Each string rider therefore rests on only three points (which gave this bridge its name): a perfectly stable construction, which offers the best basis for a firmly articulated, sustain-rich sound, because no component tilts or rattles!
