Discover the Power of OCTA PSI

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!

OCTA PSI Key Features

  • Instant Effect Order Switching: Easily switch between Octave/Pitch before or after fuzz by holding down both foot switches.
  • Flexible Output Configuration: Switch between All Wet or Wet/Dry blend with a quick double-tap of the Blend control.

The Octa Psi is more than just a tool – it’s an extension of your instrument.

Polyphonic Octave and Pitch Shifter

  • Three Modes: Up, Down, and Dual modes for creating nearly every harmonic interval, including power chords, stacked fourths, and diminished chords.
  • Momentary Mode: Perfect for dive-bombs and wild multi-octave bends.
  • Adjustable Ramp Speed: For creatively timed pitch bending, just like having an onboard expression pedal.

Transfigurating Fuzz Circuit

  • All-Analog, Transistor-Based: Delivers incredible sound with wave after wave of gain staging leading to hard clipping.
  • Three-Way Tone Switch: Carve out the perfect fuzz tone with Scoop, Punch, or Psi mode.
  • Massive Sound: Makes your guitar pickups sound enormous at any volume.

Stunning Design and Ease of Use

  • High Octane Circuitry: Housed in a proprietary angled aluminum enclosure for simplicity and durability.

Very wrinkle free and sheds off liquids well.
Color: White, Size: X-Large
Very very nice shift. I’m usually XL and that’s what size I purchased and it fits perfectly. I recently purchased one for my sons 5th grade graduation and the fit and feel was better than the 80.00 and 89.00 shirts I purchased for him at Dillard's, which were returned.

Great shirt!
Color: White, Size: X-Large
This shirt is all that! It's beautiful and feels soft yet very stable fabric. White is always somewhat see through but this one isn't bad, unless you wore black under it. My husband loves it!

Very comfortable, fits nicely with my not-so-flat tummy, gorgeous color
Color: Blue, Size: XX-Large, Color: Blue, Size: XX-Large
This is a very comfortable shirt. It feels cool when you wear it and it's slinky soft against your skin. It arrived with fold marks, but those fell out nicely after a few hours hanging. So this is a no-iron shirt for sure, which I love. I haven't tested the stain shield claims but am familiar with this material so I believe it will resist stains. It does dry quickly when damp. I love the blue color I chose. It's bright and cheerful but not tacky. The photos I posted are pretty close. The material is thick and feels like quality fabric. The stitching is single-stitch, which makes me feel that it's maybe not as durable as double stitched or crossover stitched hems. But regardless, the stitching is tight and the hems are even. The button holes durable and the firmly sewn buttons match the fabric very closely. The fit is very nice. I'm a bit stout, so slim fit shirts are too tight across my stomach if they fit in the shoulders, or too loose in the shoulders if they fit my middle. The cut of this shirt is a good compromise and it looks very nice. And the slight stretch of the fabric makes it very comfortable when I'm moving around. The collar is stiff enough to sit nicely and not flop too much. This shirt is great for casual wear but looks nice enough for a more dressy situation. I think it's a good price for a very nice shirt.
