Ready to install and use live immediately. Acoustic guitar pickup. FISHMAN Rare Earth Mic Blend. By blending the magnetic pickup and microphone, you can create a sound closer to the natural acoustic sound. This is a model after a minor change, and I've heard that the microphone is shorter and more resistant to feedback than the previous model. This product was purchased in December 2023 and installed on a guitar, so the wiring has been cut to approximately 65 cm. It was only used once after installation and appears to be in relatively good condition. It also includes the original mounting hook, so you can install it on your guitar immediately after purchase. Operation confirmed. Includes the instruction manual, hook, and the original warranty (expired). Batteries are not included. Please purchase them separately. This item has been in someone's possession. Please refrain from purchasing if you are sensitive to used items.
