    1. I'm pretty sure other NPN darlingtons would work. Like MPSA12, MPSA13 or BC517?

  4. Having built well over a hundred pedals, I would rank this one right up there. love it. BTW tried many other transistors including all the above suggestions and after sourcing 14's they were truly the only ones that worked.

  8. Built this per the layout, sounds great for the most part but for some reason the 2-octaves down setting is giving me more like an octave and a half. Double & triple checked my build, not sure what's up here. Anyone experienced this?
