The Stetsbar Tremolo system is a tremolo arm/vibrato bridge system for the electric guitar developed by Eric Stets during the late ‘80s and patented in 1995. The system was originally designed to offer an extremely stable tremolo system that could be retro fitted to “stop-tail” guitars such as the Gibson Les Paul without the need to make any permanent modifications to the recipient guitar. Since its introduction, other mounts for the system have been introduced to enable a wide variety of guitars to be accommodated. == Principle of operation == The Stetsbar is a floating tremolo system where the pull of the guitar strings are held in equilibrium at the scale length of the guitar by two heavy duty springs anchored to a spring retainer block on the base plate of the unit. When actuated by moving the tremolo arm up or down, the bridge operates with a linear motion in the same plane as the strings of the guitar. A Tune-O-Matic style bridge is mounted on the bridge plate which also holds the string anchor block. The bridge plate moves over a pair of roller bearings installed in the base plate of the unit. Thus, the bridge and string anchors move as one, eliminating any friction over the bridge saddles. Another advantage of the surface mounting of all components is that no additional holes or routs are needed to the guitar to fit the unit. This is especially nice if you upgrade to a similar guitar (e.g. from an Epiphone Les Paul to a Gibson Les Paul), as you can move the tremolo from the old guitar to the new without losing any functionality/value of either guitar, since its original bridge/tailpiece can be put back on. The Pro II Stetsbar is further equipped with a 'floating lock' system. When engaged this has the added benefit of keeping the unit in tune in the case of a string break or double stop bend. It also allows drop tuning on the fly. Use of this does mean that up pitch movement is disabled. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stetsbar」の詳細全文を読む スポンサード リンク
