I'll have another listen!
*EDIT* Yup, that's pretty much how mine sounds! It would be good for the early Black Sabbath sound - stuff like that, IMO. Bear in mind that everyone's own amp, guitar, speakers, playing style and room can dramatically affect how we hear things and how sounds are produced. I have built pedals which sound amazing (to me) through my rig and then been dismayed to find they sound rather less stellar through a friend's rig.
I like it but I'm probably not the right person for it. Thanks for posting the schematic - I'm sure a lot of players will love it!
