Wren and Cuff Box of War: Reviving the Civil War Muff
5.0/5
The Guts & the Glory
Perfecting a Legend
The original “Civil War” muffs of the 1990s earned a cult following—reportedly favored by players like David Gilmour and Thurston Moore—for a tone closely related to the Tall Font Big Muffs of the 70s, but darker and fuzzier, with a woody sustain and presence that set them apart.
The Box of War keeps the circuit’s tone intact while rebuilding the pedal around it. Wren and Cuff ditched the thin aluminum enclosures of the originals for a folded steel chassis that prioritizes weight and durability over portability, paired with true hard-wire bypass and a lifetime warranty. It’s a reissue built on the assumption that you shouldn’t need a spare.
I love all Big Muffs, and this one shines with its ability to cut through the mix with a less scooped mid-range. It sounds huge, amazing, and even with its uniqueness, it will cover your favourite muff tones.

The Verdict
The Box of War doesn’t try to reinvent the Civil War muff—it just makes sure the one you buy today survives the tour. If you’ve chased that darker, woodier take on the Tall Font Big Muff sound and always heard warnings about reliability, this reissue removes the excuse. It costs more than a standard Big Muff clone, and the steel enclosure adds real weight to your board, but for players who want that specific tone without a backup pedal in the bag, it earns its keep.
