I built this pedal in August, but had to wait to post a build report. My wife likes bats (flying foxes, specifically), and she wanted to paint a bat on this pedal...because when I told her what it was, she thought I said "Bat." It has an LM308 (precious) chip in it currently. I've tried all sorts of things in it and it pretty much sounds the same. The OP07 and the TL071 were my favorite (an aside: I know that the TL071 has internal compensation, which would negate the purpose of the external compensation cap in the circuit. However, that cap is in the circuit and the chip is in the circuit, and all I know is that it sounded pretty good. My favorite Rat tone, actually. It has a bit more sparkle to it...especially at high gain settings. I guess its double-compensated?). The LM308 is the "favorite" chip for this circuit. I don't think it does anything special. I have that chip in now because I was basically trying to force myself to figure out the magic, and am too lazy to put something else in the pedal.
When I was younger I made a decision that I thought I would have to live with for my whole life. When picking out my first distortion pedal, I went with a DS-1 (Team DS-1). I was under the impression that once you made your choice you could never deviate from it. The Rat is a really, really good distortion pedal.
When I built this pedal, I was so focused on the chip thing that I completely overlooked the diode possibilities. This one is stock (Si). I am already planning another Rat that will allow me to switch between Si, Ge, Led, and no diodes. But that's for another build report...
