Thank you for viewing. This is a "MASTERY BRIDGE M2" bridge that can be installed on JAZZMASTER, JAGUAR, and MUSTANG type models. It's truly stress-free to not have strings fall out, even when strumming the guitar vigorously. Replacement posts suitable for Japanese-made models are included. *The bridge hole diameter of Japanese-made models varies depending on the manufacturer and the time of production. Although replacement posts are included as an option only for M2, it may be possible to use the M1 posts without any problems (i.e., the included posts cannot be used). I purchased this new from a musical instrument store on March 4, 2025. I bought it for a Jazzmaster and used it for about a month, but I no longer need it because I sold the Jazzmaster. I am selling it to organize my equipment. All accessories are included, and there are no scratches or dirt, but it is not brand new, so please understand that it is a used item. Although the price is high, the product itself is very stable and reliable. I have been using Jazzmasters and Jaguars for many years, and it's great not to have to worry about strings falling out. This is probably the best choice for those who use Jazzmasters, Jaguars, and Mustangs. New ones are a bit expensive, and used ones are not very common. The prices vary depending on the site, and it's a bit difficult to price it, but I've priced it based on the market price. Please consider this opportunity. ◆MASTERY BRIDGE / M2 Soundhouse reference price: 59,800 yen ◆Mastery Bridge Replacement Bridge Offset Bridge Metric M2 Amazon reference price: 41,449 yen
