Superfuzz Bigmuff Plus Early Singles is a compilation album by the grunge band Mudhoney. The album contains the entire Superfuzz Bigmuff EP, the A-sides and B-sides of 2 singles, and 2 covers from split singles with Sonic Youth and The Dicks. It was released by Sub Pop Records in October 1990. The album is named after the Electro-Harmonix Big Muff Pi and the Univox Super-Fuzz fuzzboxes, (the title also being a play on words) which gave the band their signature dirty sound. In 2005 the album was performed live in its entirety as part of the All Tomorrow's Parties-curated Don't Look Back series.
