Hey, newbie here. I've built 4 or 5 perfboard circuits so far, and only 1 has been successful. I seem to keep having the same issue, which is that true bypass is working, the led comes on, but no sound when the effect is activated. I've triple-checked all component values, orientation for polarized components, and layout (this current one is from effectslayout - http://effectslayouts.blogspot.com/search?q=squishy). One thing I notice is that when plugged in, my DMM registers continuity between ground wires and positive wires, but not when circuit is unplugged. I'm just not sure how to troubleshoot from here. Help?
