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.
The Tru-Fi Sammy Fuzz is a faithful reissue of the vintage Sam Ash Fuzzz Boxx, originally introduced in 1967 as the Astrotone and later used by rock guitarists including Tommy Bolin and Leslie West. It is a silicon transistor fuzz in a true-bypass wedge-shaped enclosure, manufactured by Dunlop to original specifications, with three controls: Attack for fuzz saturation, Tone, and Volume delivering up to 42dB of gain boost. The circuit produces classic buzzy, gritty 1960s fuzz tones with a light treble peak, and responds differently by pickup type, screaming with humbuckers and staying warmer with single coils. It has less tonal flexibility than modern fuzz pedals, a deliberate vintage-accurate design choice, and runs on a 9-volt battery only with no AC adapter or LED.
