Electro Harmonix Ravish Sitar pedal on Bass

The reason why I used 2 cameras is because you need to see which strings I pluck in addition to the pedal configuration. Sitar has the strings you play and the strings called sympathetic. The sympathetic ones just vibrate according to the instrument&tuning, that&basically what I change, and because I was playing the E key, it gets weird. The first knob is the "Dry" nob, which bypasses the effect and outputs the original raw tone from the bass. The second knob is the "Lead", which will output the amount of effect. The third nob is the " Sympathetic", which configures how much of the vibrations of the sympathetic strings I want. The forth and fifth slides are related to the tone of the effect. The sixth (white) knob is to change between keys and modes.
