This is a phaser pedal also used by Tamio Okuda. I'm selling it because I haven't had many opportunities to use it. Thank you. Providence PHASE FORCE PHF-1 Versatile sound creation with the MIDSHIFT function The PHASEFORCE features speed control for phase shifting and output level control. It allows for a wide range of sound creation, from a gentle breeze-like sound to a radical, shaking sound. You can also adjust the level to suit your phrases. When the MIDSHIFT switch is set to the MIDSHIFT side, the phase shift band changes, emphasizing the mid-high frequencies. Built-in VITALIZER circuit A VITALIZER is built-in to prevent sound quality degradation. Even when the effect is off, the signal passes through the VITALIZER circuit, so a signal resistant to degradation is output. Multi-function LED The PHASEFORCE's LED not only indicates the ON/OFF status of the effect but also monitors the battery voltage. The LED will start to turn off when the battery voltage drops below approximately 7V. [Appearance] The exterior shows signs of use, such as scratches and wear. [Operation] Fully functional.
