Here’s what Keeley Electronics say about the Octa Psi Pitch Shifter and Octave Fuzz Pedal:

“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.”

Key Features

  • Octave Fuzz and Polyphonic Pitch Shifter Pedal
  • Extensive on-board control options for maximum flexibility
  • Momentary or Latching Pitch Shifter
  • Analogue Fuzz & Digital Pitch Shifting
  • True Bypass or Silent Buffered Bypass, user selectable
  • Top-mounted jacks for easy pedalboard mounting
  • Made in Oklahoma, USA
  • Powered by 9-18 V DC PSU (not supplied – requires centre – 2.1 mm, 150 mA current draw)

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. Octa Psi is not only powerful, but also it is beautifully designed for simplicity and durability. Its high-octane circuitry is housed in a proprietary angled aluminium enclosure, combining stunning looks with rugged functionality.

Fuzz Pedals

Fuzz drives the signal into extreme clipping, often flattening the waveform and generating a thick spectrum of harmonics. Transistor type, bias, input loading and tone filtering create markedly different responses, from loose and velvety to gated, spluttering or octave-rich. Some circuits interact strongly with pickup impedance and guitar volume, while others include buffers or blends for a more consistent response.

Tags

Analogue

The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.

Buffered Bypass

Keeps an active buffer in the signal path when the effect is bypassed. The buffer converts a high-impedance input to a lower-impedance output, helping long cables and multiple pedals retain level and high frequencies, although its headroom and noise remain part of the path.

Digital

Converts the signal or control process into numerical data for algorithmic processing. Digital designs can provide precise timing, long memory, complex routing and repeatable presets; sample rate, conversion, internal resolution and latency influence fidelity and response.

True Bypass

Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
