HD-S

Harmonic Distortion

This all new effects unit has been developed by Fumio Mieda.

The HD-S effects pedal combines three different distortion circuits to create harmonic modulation that goes beyond the traditional concept of distortion.
This all new effects unit has been developed by Fumio Mieda, developer of many famous legendary devices such as the Univibe. This new kind of effects unit differs from the usual “fuzz” or “distortion” pedal in many ways.
The HD-S lets you freely combine the three different distortion circuits to produce a wide range of previously undiscovered sounds, from the traditional fuzz to out of this world distorted sounds and more. This wide range of traditional and all new sounds means the HD-S can be used not only with guitars but also with bass guitars, synthesizers and anytime new and unique sounds are required.
One of the advantages of the Nu:tekt series is the ability to assemble them yourself. The HD-S kit doesn’t require soldering, and all of the necessary tools for assembly are included in the package. This makes it quick and easy to put the kit together, bringing you the enjoyment and satisfaction of creating your own sound.
