The Muffuletta replicates five classic Big Muff circuits as well as an original JHS version for a total of six Muff models, all analog, and each can be selected via the Mode control. JHS 2015 is more powerful, less compressed with a more haunting mid range, also the best for bass guitar. 73 Rams Head 1973-1977 V2 has a scooped mid range, less gain and is overall darker. The Triangle 1969-1970 V1 has more low-end response and is more articulate. The Pi 1977-1978 V3 (not the 2000 redesigned NYC version) is more aggressive sound. The Russian 1999-2009 V8 has less clarity and less low end. The Civil War 1991-1993 V7 has more mid range, brighter overall tone and less gain. Never before has there been a single pedal that gives you all these different eras of its tone.
