And I cannot lie.
But seriously, as someone pointed out the clones seem to be more popular than the OG models. I am guilty as well. I had a black Russian for a while, but every used it. I tried using a Supercollider, a Pickle Pie B, and a Hail Satan Deluxe and just never cared for where I ended up in the mix. I have a Grey Stache collecting dust in my closet now.
My personal take is that unless you want to be just guitar support, or replacing a guitar, you need a blend of some kind. Otherwise you vanish in the mix. Maybe that is what some people want.
I liked the Supercollider and Grey Stache the most. I also like the Team Awesome Fuzz Machine. Different clipping circuit than a Muff, but the blend is phenomenal.
