I give you the Hoss Booster Deluxe – a modified MKC with bass boost, ultra gain mod and a 6 way diode selector to choose between Ge, Si, Schottky, and 3 asymmetrical combinations of them. A nod to the “K” with the gold finish and mythical creature adorning the face (Bernie is about as common as a Centaur these days…). I also am currently using a TL082 in the IC2 position…I don’t know why, I just tried it. Enjoy!
