Jam Pedals · pedal
The JAM Pedals Fuzz Phrase Si is a handcrafted silicon transistor Fuzz Face-style pedal built in Athens, Greece. Using carefully selected silicon transistors rather than germanium, it delivers a brighter, more aggressive fuzz character with greater consistency across temperature ranges. The silicon circuit produces a tight, cutting fuzz with strong upper-harmonic presence, suited to high-gain rock, grunge, and alternative styles where temperature-stable operation and a modern fuzz edge are valued. Unlike the germanium variant, the Fuzz Phrase Si holds its character in hot stage environments and does not drift with ambient heat. Players appreciate it for its ability to produce classic Fuzz Face tones with added clarity and punch, pairing well with single-coil guitars and driven tube amplifiers.
What stands out
“The silicon character is crisper and more consistent, making it better suited for high-output humbuckers or players who want a controlled fuzz , warm one”
