Carl Martin Heavy Drive

Just noticed we didn't have any CM designs on the library yet. Demo vid i found isn't the greatest quality, but it has a Dinosaur Jr. riff, followed by some White Stripes, so i just had to post it. Made me feel like 25 all over again. Pedal seems like a nice distortion unit too. The low noise MC33097 quad opamp may be required for best results, but i see no reason why TL074 or LM324 wouldn't work here too.
