Just had a comment from a studio who had recently used the Fuzz Moo for one of their clients. As a test, they placed the Moo along side a Big Muff and another insanely expensive boutique Fuzz for sonic comparison. After running all three blindly and this musician having his pick of the best tone he heard from the three, he picked the Moo! Stating both power and warmth. The studio was pleasantly surprised and confirmed what they were hearing as well. Great tone and a great value... indeed a Big Muff eater !!
