OD-S is an analog overdrive pedal kit from Korg’s NUTEKT brand.  It was announced at Winter NAMM 2020 and was available as part of several DIY workshops at the Korg booth, where I built it. It’s based on Korg’s new analog triode vacuum tube, designed to give the same performance as conventional vacuum tubes in a more compact and stable form. In this video I quickly walk you through the build process and run synth and guitar sounds through it (with the kind help of Static from Korg):
