The Harvezi Hazze is a seriously interesting distortion pedal. That vintage UJT waveshaper gives it a unique, almost vocal-like distortion that's really cool for experimental rock, industrial, or anyone wanting to escape the usual overdrive sounds. It’s a premium-priced option that rewards those willing to dig in and explore its unusual character.

Frequently Asked Questions

UJT waveshaping produces a more asymmetrical and complex distortion, often with a smoother, more organic feel compared to traditional diode clipping.
It’s a fairly noticeable compressor, designed to add sustain and tighten the low-end; it's not a transparent, subtle compression.
Spoil sets the threshold for waveshaping, while Spread controls the intensity of the folding; adjusting both allows for a wide range of distortion textures from subtle grit to full-on chaos.
