Paul Gilbert yes, but I don't think it's supposed to be based on the colourbox. I remember reading that the PG-14 is based on two older pedals that JHS did - the haunting mids (sweepable mid boost/cut) and the super bolt (which is a FET simulation of a cranked supro). Then they did some circuit tweaking to put emphasis on frequencies that work with Gilbert's ears (since he has some hearing damage that apparently kills certain frequencies).
