Keeley Octa Psi

Introducing the Octa Psi Transfigurating Fuzz Pedal, the ultimate combination of polyphonic Pitch-Shifter, Octave Generator and Analog Fuzz! Imagine merging a powerful pitch-shifter, octave generator, and analog fuzz into one intuitive pedal. With the new Octa Psi, we’ve made that dream a reality!

Octave/Pitch before or after fuzz? Well, now you can experience the best of both worlds, simply by holding down both foot switches on the Octa Psi at the same time to switch the effect order. For even more control, a quick double-tap of the Blend switch allows you to seamlessly toggle between an All-Wet effect or a Wet/Dry blend, while with a simple press and hold of the Fuzz switch, you can seamlessly shift between momentary and latching octave modes, giving you immense additional options to tailor your sound.

The polyphonic octave and pitch shifter features three distinct modes: Up, Down and Dual. These unlock an array of possible harmonic intervals ranging from power chords to stacked fourths and even diminished chords across a +/- two octave range. Momentary mode is perfect for wild dive-bombs and multi-octave bends, while an adjustable ramp speed adds creative flair by letting you control pitch bending just as if you had an in-built expression pedal on board.

With its all-analog, transistor-based fuzz circuit, Octa Psi brings wave after wave of gain staging, making your pickups sound enormous and leading to full on hard clipping and immense tones on tap. With the three-way tone switch, you can easily dial in your desired fuzz tone by switching between the Scoop, Punch, or Psi bass response modes.
