TonePros T1ZS Tailpiece Standard Thread 5/16-24 – Black

Angkor Music — Why Upgrade Only the Tailpiece, Thread Specification, and Brass Studs

The T1ZS is the standalone tailpiece for players who want TonePros locking performance without replacing the bridge — either because their existing bridge is already adequate or already a TonePros model, or because their budget or preference targets the tailpiece as the single upgrade. On a stop tailpiece guitar, the tailpiece is where the strings anchor — it is the rearmost fixed point in the string path and the component whose stability most directly affects how completely string energy enters the instrument body. A standard production stop tailpiece sits on its studs under string tension but is not locked — it can micro-shift on the studs, particularly under aggressive playing or temperature-driven wood movement. TonePros' locking system uses set screws to lock the T1ZS tailpiece positively onto the stud heads once the guitar is set up — eliminating micro-movement at this critical anchor point and allowing more complete transfer of string vibration into the resonant body. The 5/16-24 US thread is the standard thread for Nashville-spec stop tailpieces on most US-made and US-spec electric guitars — Gibson USA, Epiphone and most similarly-spec'd instruments use this thread. Confirm your existing tailpiece uses 5/16-24 thread and 82mm stud spacing before ordering. The Zamak body and brass studs follow TonePros' consistent material philosophy across the range: Zamak for structural precision in the body housing, brass at the stud contact points where density and resonance transmission matter most. The 13mm stud caps provide the contact interface between the tailpiece body and the studs. For the full TonePros locking system explanation see any TonePros bridge product page.
