I've always loved the way that John Petrucci's guitar has sounded, specifically the depth that his delays add to his sound. I know that he uses Eventide Timefactors, and he has one (two?) set to two different delay times, one being the half of the other (i.e. 600ms on one and 300ms on the other). I want to get that same delay sound, but I don't have $400-$800 to spend on delays alone, so I was thinking of getting two EHX #1 Echos and setting one to half the speed of the other. How well do you think this would fare for me?
