The Staytrem tremolo for Jaguar / Jazzmaster is a replacement for the standard arm and collet which overcomes the problems normally associated with these guitars.
Eliminates loose and rattling tremolo arm.
Virtually no free play so no lost motion.
Designed to stay in place when released.
The collet has an internal nylon sleeve so no metal to metal contact with the arm.
This provides a smooth rotation and will last for many years.
