This is an auction for an ARTEC piezo pickup A1-OSJ. It's an easy-to-install piezo pickup for acoustic and electric guitars. I bought it new a while ago, but I only checked to see if it would fit, and as you can see in the photos, it's in beautiful condition. ※) There are minor scratches and scuffs that are barely noticeable. I also checked the operation before listing it, and confirmed that it works without any problems. It's a popular model for its good sound quality and low feedback. I used the included adhesive for attaching the pickup to the guitar, so please use a "reusable double-sided tape" available at home improvement stores. Also, please note that the cardboard backing, which also serves as the instruction manual, has a crease in the middle as shown in the photos. I plan to ship it via "Yu-Packet Post mini" with free shipping. Also, since I am also listing it on other sites, please check the stock in the comment section before purchasing. Please forgive me if it is sold out.
