This is a Takeuchi-made F, R tremolo unit that was on a Fender Japan Stratocaster released about 15-18 years ago (or maybe even earlier). (Personally, I think they surpassed the originals around the time the F.T. models came out.) I thought it was revolutionary that the block wouldn't fall out even when turned upside down! However, the blocks for the 4th and 6th strings have cracked and been replaced. The arm bar has also been replaced with a silver one, approximately 16 cm long. At that time, I slightly bent the arm bar screw because I didn't like the arm bar dangling and hitting the fine tuners. It's probably looser than Brad Gillis' setup. Those who prefer a loose feel should adjust the arm bar accordingly. Please check the condition in the photos. Shipping will be via regular mail (with tracking). No returns or exchanges. *The unit will be disassembled from the block for shipping.*
