Cusack Music Tap-A-Phase (Cusack Music Tap-A-Phase) Tap tempo-enabled phaser pedal. I've used this for live performances for about two years, and overall, it's in good condition. However, the mode select knob on the upper right is missing. The shaft can be easily turned, so there's no problem with operation. Operation has been confirmed. The items shown in the photos, such as the main unit, original box, and instruction manual, are included. It can be powered by a 9V center-negative adapter. A vintage-like 6-stage phaser based on analog circuits. In addition to controlling the LFO rate with tap tempo, you can select multiple waveform modes (sine/triangle/square). This is a unique pedal that combines a thick sound with a wide range of sound-making possibilities. I'm selling it to organize my equipment. Instant purchase is OK.
