Stereo chorus effect unit that achieves a variety of effects. - Model: SPH-1 - Type: Stereo Phaser - Controls: RATE, DEPTH, RESONANCE - Output Terminals: OUT 1, OUT 2 - Back: With Velcro - Switch: ON/OFF Pedal Thank you for viewing. This is a stereo phaser from ARION. I purchased it several years ago and used it a few times indoors, and have stored it in a dark place. There are no noticeable scratches. Operation has been confirmed. The switch has been replaced, but it is not true bypass. Due to the switch replacement, battery operation is not possible. Velcro is attached to the back.
