The Korg Nu:Tekt HD-S Harmonic Distortion Pedal is perfect for players looking to build their own unique clipped sounds - from the fuzzy to the ferocious! It features three separate distortion circuits and all the tools you need to create the effect, in addition to four on-panel knobs and three hidden controls to unlock an enormous range of harmonic distortions. And thanks to Korg's streamlined build process, it's a breeze to get the HD-S up and running. It includes all the necessary diagrams and doesn't require any soldering - so you can create your own sound from scratch in no time at all. Stemming from the creative electronic music legend Fumio Mieda, the HD-S can take your tone from the tame to the tempestuous.
