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.
The JAM Pedals Eureka Fuzz V2 is a handmade Greek boutique fuzz pedal based on the Shin-ei FY-6 Super Fuzz circuit from the late 1960s. It delivers a thick, harmonically rich upper-octave fuzz with strong midrange character and a distinctive woolly texture. The dual-octave coloring gives guitar notes a singing, almost synth-like shimmer when played in higher positions. JAM Pedals hand-assembles each unit in Athens, Greece, using carefully selected components to maintain circuit authenticity. The Eureka Fuzz V2 suits psychedelic rock, garage rock, and classic fuzz tones where upper harmonic content and mid-forward aggression are priorities. It responds well to guitar volume knob adjustments and rewards players who want a pedal with a pronounced, character-driven identity rooted in vintage Japanese fuzz design.
