Purchased around the beginning of September. Used sparingly. No operational issues. A wireless system perfect for pedalboard integration, in a compact pedal size. Automatically establishes the optimal wireless connection, significantly reducing setup time and effort. BOSS's proprietary wireless technology provides high-quality sound and stable connection with an ultra-low latency of 2.3ms. (Transmission range: 20m) The transmitter has a built-in rechargeable battery, allowing for up to 12 hours of continuous use. Charging and automatic wireless connection are possible simply by connecting the transmitter to the receiver's docking port. Cable tone simulation that reproduces the natural sound changes when using a guitar cable (OFF/SHORT/LONG selectable). The receiver uses a dual power supply system: a separately sold AC adapter PSA-100S, or two AA batteries. When using the AC adapter PSA-100S, the receiver's DC output terminal can be used to power other pedals using the separately sold parallel DC cord PCS-20A.
