Despite my deep respect for Marc, I've never gotten along with any of his fuzzes. I've owned and sold the Ernie, the Zero, the Mayo, the Screwdriver, the and the ? Lady. They all had in common something that is inherent to the Big Muff itself, a sort of artificialness that is just not organic and amplike. It sounded so fake and trebley that I just couldn't keep them in my rig. A nice TGP'er put up a Top Fuel in the Emporium for a song, and I figured I'd give Skreddy one more try before giving up on his pedals. I am so happy that I did. I have NONE of the complaints that I did with the previous pedals. So natural, powerful, singing with a delicious bite. It sounds like there is a BM tone stack in my amp's preamp. It's just awesome. Too bad this pedal is discontinued, but if you don't have one, and if you are like me and not a fuzz guy because they dont' sound organic, you need to try this out. Wow.
