Ben sent in his tremolo effects pedal that he made out of a couple of 4066 IC's. The circuit has its limitations, since it is based on an LED chaser, but the overall effect is pretty cool. Ben is a long time reader, and a first time submitter to the MAKE blog. Let's hope he makes some more cool projects and shares them with us in the future. - Link
