Gotoh 201B-4 G Bass Bridge

The Gotoh Hi mass bridge fits in the standard spacing of 70mm of the screws. Installation is easy, reuse the original screws for they were bigger and fit the holes right. The benefits are that there is a gain of sustain and it eliminated a dead C on the D string. More precise playability, same for intonation of the bridge. More pitch stability, tuning is easier. Side effect, it helps to cure the neck diving. More even response across the frequencies, highs more in control, the E string is more defined and played, also on the high register.
