I got this off of the L sound website. Pretty cool huh? No wonder the thing sound so good.
If you don't know who Mike Beigel is, he is the designer of the Original Musitronics Mutron III. We all know what a gem that is
L Sound is a company that does Effects Pedal repairs and does most of it's work on vintage Mutron Products.
