Keeley Octa Psi Pitch Shifter and Octave Fuzz Overview
The Keeley Octa Psi Pitch Shifter and Octave Fuzz is a dynamic and versatile pedal that merges three powerful effects: polyphonic pitch shifting, octave generation, and analog fuzz. This pedal allows musicians to explore a wide range of sonic possibilities by combining digital pitch effects with rich, analog fuzz. Here’s a detailed overview of its features:
Key Features:
Polyphonic Pitch Shifter & Octave Generator:
- Offers three distinct modes: Up, Down, and Dual. These modes allow you to create harmonically rich intervals like power chords, stacked fourths, and diminished chords, covering a range of +/- two octaves.
- Momentary and Latching Modes: Quickly toggle between momentary (perfect for dive-bombs and multi-octave bends) and latching for more sustained effects.
Analog Fuzz Circuit:
- The fuzz circuit is all-analog and transistor-based, delivering powerful gain staging and full-on hard clipping for immense, gritty tones. It makes your pickups sound massive and is ideal for creating crushing fuzz tones.
- Three-Way Tone Switch: Choose between Scoop, Punch, or Psi bass response modes to dial in the perfect fuzz tone, ranging from mid-scooped to tight low-end punch.
Effect Order Switching:
- You can change the order of the octave/pitch and fuzz effects by simply holding down both footswitches. This feature allows you to experience the difference between running octave before or after fuzz, offering flexibility in shaping your tone.
Blend Control:
- With a quick double-tap of the Blend switch, you can toggle between an all-wet (100% effect) signal and a wet/dry blend, offering additional versatility depending on the effect you’re after.
True Bypass or Silent Buffered Bypass:
- Choose between true bypass for a direct signal when the pedal is off, or silent buffered bypass for improved signal clarity, especially in larger pedalboard setups.
Adjustable Ramp Speed:
- Control pitch bending with the Ramp Speed feature, simulating the effect of using an expression pedal to add smooth transitions between pitch shifts.
Power & Build:
- The pedal is powered by a 9-18V DC power supply (not included, requires 2.1mm, 150mA current draw).
- Built for durability, the pedal comes in a proprietary angled aluminum enclosure, designed for both aesthetic appeal and rugged functionality.
Top-Mounted Jacks:
- Designed for easy pedalboard integration, the top-mounted jacks help conserve space and reduce cable clutter.
Sound and Tone:
The Octa Psi excels at blending pitch effects with fuzz to create expansive and immersive soundscapes. The analog fuzz adds layers of rich, harmonic distortion, while the pitch shifter enables creative control over octaves and harmonic intervals, making it perfect for everything from classic fuzz riffs to experimental, avant-garde soundscapes.
