Imagine having your favorite pitch-shifter, octave generator, and analog fuzz all in one pedal. A dual effect designed to inspire musical adventuring. That's what the new Octa Psi Transfigurating Fuzz is all about. The all-analog fuzz and distortion features a powerful transistor design that will make any bass or guitar pickup sound massive. The fast tracking polyphonic pitch-shifter offers a symphony of sounds to explore. Drop tuning, familiar and new pitch-shifting combinations, and even unexpected chorus-inspired sounds just to name a few. Why settle for static Fuzz into Pitch Shift or Pitch Shift into Fuzz settings? With the Octa Psi, you don't have to be binary. On-the-fly commands include switching the effects order, going all-wet, and even True bypass to Buffered Bypass modes. Plug in for Remote use or use a TRS Expression Pedal to control the pitch bending parameters and dive-bomb your heart out. The Octa Psi delivers mind-blowing sounds and visual impact in a newly designed aluminum enclosure with the quality you would expect from Robert Keeley. Welcome to a new era of Keeley Electronics.
