Tone Monk effects have been around for a while now. He's run into a little trouble recently: http://freestompboxes.org/viewtopic.php?f=6&t=15903 (The shortened version is that he's been building lots and lots of "his circuits" using PCBs he's blagged for a knock down price from Madbean (and possibly General Guitar Gadgets) by pretending he was using them in an educational manner *AND* that all his circuits are ripped off - but that's nothing new now is it!). However, the Tone Monk pedals are still very popular so I thought I'd cover a few! First up the "Seed of Life", here's the official Tone Monk description:

So there you have it, if you want to build one buy a GGG pcb and get building.
