This pedal is not a clean octave up; it adds dirt and grit, creating harmonic extensions and a vibrating sound similar to a ring modulator.

Critic Reviews

Henretta Engineering Purple Octopus review on pedal-of-the-day.com

pedal-of-the-day.com

The Henretta Engineering Purple Octopus is a tiny yet mighty octave-up pedal, praised for its simplicity and compact size. With a single stomp switch and two internal trimpots for volume and intensity, it offers adjustable control over your sound, from subtle enhancements to full-blown sonic transformation. While its focused power on higher registers delivers fun unpredictability, it's mainly effective on higher frets, which might not suit everyone. Overall, it's a unique addition to any pedalboard, ideal for those seeking an innovative effect in a minimal footprint.
