I am selling this because I accidentally purchased it. The price is lower than the purchase price, so I think it's a great deal. Specifications ◆Model Name: VG300 ◆Finish (Color): GG / Gold ◆Type: Tremolo Unit ◆String Pitch: 10.8mm ◆Contents: Tremolo body, arm, studs, springs, spring holder, holder set screws, wrench, instruction manual A classic tremolo unit, Wilkinson!! This is a surefire item, standard equipment on high-end brand guitars. Made in Japan by GOTOH, known for its high quality and premium parts!! There is no other company in Japan that can produce products of this quality. While the Wilkinson tremolo's standard model, the "VS100," has block saddles, this "VG300" has bent saddles, showing a further pursuit of sound. The stud position is the same as the VS100, so no difficult work is required, and it can be replaced simply by swapping it out. The nut and bridge (tremolo unit) are where the vibrating strings first transmit their vibrations. If you cut corners here, even a good wood body and neck are meaningless. Please refer to the GOTOH official website for the diameters and sizes of each part.
