This listing is for a Yamaha PH-01 Phaser.

I am the second owner of this pedal, and it has seen prior use before it came into my possession, as evidenced by the light wear on its surface at the edges.

For its stay with me, it has only seen light studio use, and is in good working order.

This pedal was originally designed as a part of Yamaha’s Professional System Effector series, and was thus powered via their SB-100 Professional System Board, or a 9 volt battery. I have included an adapter (pictured) so that it can be used with a standard 9 volt supply (i.e., Boss PSA-120).
