This tremolo unit is the flagship model of GOTOH, bearing the number 510 (Gotoh). GOTOH's own patented features, such as a secure stud lock mechanism and an arm with adjustable torque, and the FST mechanism that secures the strings in a hollow space to maintain more consistent tension, are all incorporated with the best of Japanese technology without compromise. Also, this model uses a one-piece steel saddle. Its substantial weight provides a tight and attractive tone. Long and beautiful sustain, clear sound definition, and the highest tuning accuracy. 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.
