So basically it's making your volume control into a tone control? Or am I not following?bridge the outer contacts on the volume pot with a 250pf cap and a 220K resistor..... I go play a gig - I leave my Mo'D on all night long. Roll the volume down to 5'ish and get a nice fat rhythm tone and crank it for searing solos.... There are a lot of shades of distortion in between.
