The Amptweaker FatRock is a warm-voiced rock distortion pedal designed by James Brown, creator of the Peavey 5150 circuit. It is the darker, lower-mids-focused sibling of the TightRock, featuring a fixed Fat boost at the front end that reduces high-frequency aggression and extends the low range of its Tight and Tone controls. Aimed at players with bright guitars or amps who want warmer rock distortion, it includes three-band EQ with a PlexEQ switch for vintage stack tones, a SideTrak loop that activates when bypassed for clean effect routing, and a standard effects loop with Pre/Post switching. A retweaked noise gate handles the reduced top end smoothly. Best fit for classic rock and hard rock players seeking a thick, cab-like low end without excess sizzle.
