I'm intrigued by the Lemon Drop (or ZII) from Lumpy's Tone Shop.
http://www.lumpystoneshop.com/lemondrop.htmThere's some speculation about the circuit on DIY Stompboxes, but nobody knows for sure. A schematic is NOT available, so someone who has one would have to do some detective work.
I'd love my work to be as clean and neat as Lumpy's.
Thanks!
