İbanez Edge Black Tremolo-2ED1R31B
String Spaces: 10.8mm
The Edge tremolo is a double locking tremolo bridge developed and manufactured by Gotoh for Ibanez. It is sometimes referred to as the "Original Edge" to differentiate it from the various versions that have been released since. The Edge is acclaimed by many guitarists as the finest trem system available in the market.[1] It was introduced in 1986, discontinued in 2003 and brought back in 2010
The Edge is based on the original, patented Floyd Rose tremolo design which Ibanez & Gotoh licensed. As such it incorporates a double locking design, meaning that the strings are retained at both the bridge and the nut. By effectively minimizing the length of string the Floyd Rose design allows players to perform crazy manipulations of the tremolo while enabling the guitar to return to tune when the tremolo was released. Fine tuners on the bridge facilitate tuning without unlocking the nut. As with the traditional Fender-style synchronized tremolos which came before, the Floyd Rose used a set of springs and an adjustable claw located under the guitar body to equalize the tension of the strings and allow the tremolo to float. A set of six saddles which can be moved independently forward or backward to achieve intonation retain the strings at the bridge. Meanwhile the Top-Lok III locking nut pairs with the Edge to secure the strings at the headstock.
