This tremolo unit is the flagship model of GOTOH, bearing the number 510 (Gotoh). GOTOH's own patented features include a reliable stud lock mechanism and an arm with adjustable torque. The FST mechanism, which secures the strings in a hollow space to maintain more consistent tension, is just one example of the uncompromising use of the best Japanese technology. ★ The difference between the 510T-SF2 and the 510T-FE2 is the saddle! The SF2 uses a bent-type saddle, producing a natural and warm sound. The FE2 has an integrated saddle, resulting in a clear sound with excellent sustain. The SF2 is recommended for those seeking a more natural sound or an old vintage sound. Of course, the tuning accuracy is still the best! As expected of GOTOH's flagship model, this is a truly exceptional product. The nut and bridge (tremolo unit) are where the vibrating strings first transmit their vibrations. If you cut corners here, even a body and neck made of good wood will be meaningless.
