The Gotoh 510TS-FE1 tremolos are designed to withstand years of abuse and remain trouble free. This tremolo is precision machined and paired with steel saddles meant to last a lifetime. The patented FST tremolo block is designed to allow the strings to contact the saddle without touching the block as it passes through which increases sustain and tuning stability. The 510TS-FE1 also uses Gotoh’s patented Stud Lock system for increased mounting stability. Hardware included.
