The P-4 Routing Box series inherits the quality of the P-1, P-2, and P-3 series, which have received overwhelming support from many musicians since their release in 1999, while reducing costs by reviewing production efficiency. We realized this. This is a hand-wired product that uses carefully selected parts and a wiring method that has excellent sound quality and is resistant to noise.
The P-4TB has a true bypass function that completely bypasses effects connected between send and return. Some effectors have low input impedance, so simply connecting them causes a deterioration in sound quality, and some effectors always pass through a buffer even when the effect is turned off, making it impossible to bypass this buffer. The P-4TB is very effective when you want to solve the problem of sound quality deterioration that occurs throughout the company, or when you want to avoid buffered sound.
