I have been using about 7month, became big fan. Innovative that feels history. New fuzz sound like. distortion algorithm can be analog or digital. astonishingly the get fluctuation of device between analog~digital !!! Distortion module is even when used alone pretty tasty of high quality. Moduration mode: OSC my favorite. Modulates faster add solid, rich overtone. in LFO shape and modulation speed, filter/distortion order of things or ON/OFF.There are endless combinations.
