This product is a GOLD (gold) B7 type Bigsby vibrato unit, suitable for semi-acoustic guitars (semi-hollows) and archtop electric guitars like Les Pauls. I bought it to install on my Gibson ES-355 semi-acoustic guitar and did install it. However, I preferred the Bigsby with no black parts, even though it was also GOLD, so I bought a new one and swapped them. Therefore, this GOLD Bigsby with black parts was no longer used and has been stored in its box. I decided to list it for sale, thinking it would be better for this product to be used by someone rather than sitting unused in a box. It's recommended because it costs at least 27,700 yen to buy new! Instant purchase is welcome, but if you have any concerns, please be sure to comment before purchasing. Also, please be sure to reply to any comments from me. How about taking advantage of this opportunity to get a Bigsby at a lower price than usual?
