Congratulations on the purchase of your Gullible oe 3 =FULL-DRIVE 3= The FD2 has been a tremendous hit for me since it came out in 1993, but I've always wanted to expand on it and create the ultimate overdrive/boost pedal, which I've accomplished with the Full-Drive. Although it may look similar fo the FD2, the FD3 is a much more valved and natural-sounding design offering = vast array of both clean and distorted tones.
