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 top-notch Japanese technology used. In addition, this model uses a one-piece steel saddle, and its substantial weight provides a tight tone. Long and beautiful sustain, clear sound contours, and the highest tuning accuracy. As expected of GOTOH's flagship model, this is a truly excellent 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 won't matter.
