This is a very rare backplate silent single-coil system for electric guitars. It's new, but the hinge on the package is damaged. There is no particular problem with the contents. I bought it for my Stratocaster, but when I opened it, my guitar already had an SSC installed, so it's unused. It's almost impossible to obtain in Japan. This type is also very difficult to obtain overseas and is valuable. - Model: Suhr BPSSC System - Type: Backplate Silent Single-Coil System - For: Electric Guitar - Included: Instruction manual, wiring diagram
