The TT50 (alternately TT-50) is a synchronized tremolo bridge developed and produced for Ibanez. The TT50 was introduced in 1995 on the Talman series guitars.
The TT50 employs a non-locking, double pivot design which is reminiscent of traditional Fender tremolos. The double-pivot design wherein knife edges on the tremolo plate pivot against a pair of studs mounted in the body is slightly more complex than the simple six-point standard tremolo, but less complex than the Floyd Rose-style design of the Edge. Below the bridge is a metal block to which a pair of springs are attached to a claw mounted to the body. These springs offset the tension of the strings allowing the bridge to float.

The height of the TT50 bridge can be adjusted by raising or lowering the height of the studs in the body. Additionally six individual brass rod-style saddles allow the height of each string to be set by adjusting a small allen posts on either end of the saddle. Intonation of each string is adjusted by moving the saddle fore and aft using a screw which runs through a bar that is bolted to the back of the bridge plate. The tremolo arm of the TT50 is 6mm in diameter and threaded to screw into the tremolo base.
The TT50 appeared in several models of Talman guitars. Other synchronized tremolos offered on Ibanez guitars in the same period include the TZ30 and TZ100.
The TT50 last appeared in 1998.
