Selling to organize my equipment. No box or accessories, only the main unit. Product Description: Equipped with a "real buffer" that strengthens the sound core without changing the sound quality for IN and OUT. It prevents sound quality degradation and noise interference, providing clear and well-defined sound within the effects system. It also functions as a junction box. By using this unit, the terminals for connecting the guitar and amplifier are consolidated into one place, eliminating problems caused by plugging and unplugging, and enabling a smooth setup on the effects board.
