From the post
Here's another plexi-in-a-box pedal. Fairly simple in comparison to others. I've drawn 2 layouts for this one; one stock and one with an adjustable gain mod. The EQ switch is optional, as some who've built this circuit say it's pretty lackluster. The original uses an MC4558CN, but just about any dual op-amp should suffice (try JRC4558, TL072, NE5532, etc).
