Good. It's always best to experiment with placement, amount of gain, EQ and stuff like that.
That being said, I have my Klon/e placed at the very end of my chain as an almost always on (mostly clean) boost. Really the only time I'd switch it off is if I've got a fuzz on and it's takin' the edge off of the fuzz.
I tried a Soul Food when skully lent me one. It's just OK as an overdrive and not worth it as a clean boost. Doesn't really sound like a Klon. I also tried a Madbean klone he built at the same time (which sounded very close to a Klon).
Haven't tried the IdiotBox. So, can't comment on it.
I recently picked up an Earthbound Audio klone built on an Aion Electronics board. It's not really gettin' along with the guitar/amp set-up I've got here.

The good thing is the diodes are socketed. So, I intend to try out some other diodes.
Don't even ask me about the buffer. (As I've said, it's almost always on. So, I never use the buffer.).
Hope that helps.
