Multifunctional wireless microphone system with volume adjustment. SKYSONIC acoustic guitar pickup. This was produced this year, used once, and then stored. It's a wireless system, so you don't need to modify your guitar to use it. It's a very convenient pickup. This is a Shimamura Music limited edition color. I heard from the manufacturer that due to requests from professional musicians, a minor change was made to this 2025 version, allowing sound to be output via a wired connection. A dedicated cable is available as an option. This time, that cable is also included. I only tested the cable to make sure it worked, but I haven't actually used it. There is a small scratch next to the green LED on the surface, but it doesn't affect the operation. I lost one of the two included charging cables, so I'm including a longer cable. No returns or exchanges accepted.
