Purchased in December 2024, opened on December 3rd, and only tested at home. It's a beautiful item, practically new. I may still use it until it sells, but I'm handling it with great care. Please feel free to ask any questions. This WL-20 is designed for passive pickups, but my guitar has active pickups, and I realized my mistake after purchasing it, leading me to list it for sale. There are absolutely no issues with the unit, and it is fully functional. It's optimized for passive pickups (like the pickups on electric guitars that don't use batteries), so please confirm that your guitar has passive pickups before purchasing. I tested it with a passive Telecaster, and it performed just as well as a cable connection, with no noticeable delay. If you don't make the same mistake I did, it's a very good product. The original box and all included items are as they were when I bought it, so I will ship it as a new-like set. Thank you.
