The patented VT system (ES 1119430 U) is based on two basic principles: the adaptation of the bridge dimensions to the existing standard cavity in the ST models and the bridge pivoting system. Adapting the dimensions aims to allow the bridge to freely enter into the cavity of the guitar body by pulling the whammy bar back (tensioning the strings) and requires a redesign of the complete assembly (saddles, plate and block). To optimize the movement of the bridge, the pivotal center of action has been changed by adding a part (fulcrum) that replaced the traditional concept of support on screws, giving more amplitude to that movement. The shape of the point of support of the plate on the fulcrum has also been changed, minimizing friction, which is practically non-existent. The result is a homogeneous action very pleasing to the musical performance totally free of unwanted noises. (It is recommended to use low friction nuts and locking tuners).
