ESP Custom Lab / Tremolo Tone Spring Type-2 New, unopened product. These tone springs were developed by focusing on the effect that tremolo springs, which support string tension, have on sound. Springs are also an important factor in building the overtone structure of string vibrations, and especially in floating tremolos, which have few points of contact for transmitting string vibrations to the body, the sound image becomes thicker by increasing the number of springs and strengthening their foundation. However, simply increasing the number of springs can cause problems such as making floating impossible or the springs detaching when pulled up because they are fully compressed. ESP Custom Lab has developed soft and flexible springs to solve these problems. TYPE-2 achieves enhanced high-mid range frequencies by increasing the wire diameter and the outer diameter of the spring while maintaining flexibility. It is designed to have a slightly stronger tension, and it is possible to control the tone and tremolo touch not only with TYPE-2 alone, but also in combination with TYPE-1 or conventional springs. #Tomo's Guitar Parts Listings
