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, as well as 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. Furthermore, this model uses a one-piece steel saddle, and its substantial weight provides a tight tone. Long and beautiful sustain, clear sound definition, and the highest tuning accuracy.

If you cut corners here, it won't matter how good the body and neck wood are.
