Electro-Harmonix Triangle Big Muff
Brand: Electro-Harmonix · Category: Fuzz · Released: 1969

The earliest Big Muff voice: huge sustain, rounder attack, and less polite fuzz-wall authority.
The Triangle Big Muff is the first major Big Muff flavor: thick, sustaining fuzz with a smoother top end and a rounder feel than many later versions. It still has the classic Muff problem — scooped mids can vanish in a loud band — but for singing leads, heavy rhythm walls, and vintage fuzz sustain, this is the source code with better shoes.
