From the post

Marketing speil says this is a "reel-to-reel saturator overdrive" that is inpired by Akai GX 210D reel-to-reel tape machine. You might get similar sounds out of this circuit which is basically a SHO with three separate clipping switches for each clipping mode. Not sure why they did this since you can get similar clipping options with a single SPDT on/off/on switch...
