JAM Pedals Monterey ’67 Mini Multi – RetroVibe mk.4 y Fuzz Phrase Si

JAM Pedals Monterey ’67 Mini Multi – RetroVibe mk.4 and Fuzz Phrase Si in a limited edition

RetroVibe mk.4 · Fuzz Phrase Si · Analog Uni-Vibe · Silicon Fuzz Face-style · BC107 · Tap Tempo · Ramping · Only 10 units · Handmade and hand-painted

The JAM Pedals Monterey ’67 Mini Multi brings together two of the most iconic late-60s sounds in one compact enclosure: the psychedelic pulse of the RetroVibe mk.4 and the vocal, dynamic, harmonically rich fuzz of the Fuzz Phrase Si.

This limited edition is built around a very specific idea: fuzz, vibe and cranked amps. Two effects that already belong to electric guitar history on their own, but together open the door to the world of Monterey ’67, psychedelia, blues rock, burning solos, breathing chords and liquid modulation wrapped around a living fuzz tone.

In terms of sonic family, the RetroVibe mk.4 is one of the most respected interpretations of the Uni-Vibe / photocell vibe world: analog modulation with Chorus and Vibrato modes, delivering that vocal, three-dimensional pulse that can move from slow liquid waves to fast rotary-like motion. The mk.4 version expands the Depth and Speed range, adds Tap Tempo and Ramping, and supports a standard passive 10k expression pedal for real-time Speed control.

The Fuzz Phrase Si takes the spirit of the silicon Fuzz Face family into JAM territory. It is built around BC107 transistors, selected to preserve sustain, guitar-volume cleanup and harmonic richness, while adding the stability and consistency of silicon. The goal is to capture part of the magic of vintage germanium-style fuzz circuits without their temperature sensitivity and inconsistency.

The combination is the point: the fuzz brings saturation, sustain, attack and wild response to your guitar volume; the vibe makes everything breathe, move and become more three-dimensional. Use each effect separately, or step straight into the classic fuzz + vibe territory — one of the most beautiful pairings for solos, riffs, psychedelic textures and huge amp-like tones.

Only 10 units of the Monterey ’67 Mini Multi were made. Each one is handmade by Tasos and hand-painted by Stenia, making it more than just a two-effect combination: it is a short-run Custom Shop piece with its own character, vintage inspiration and late-60s visual identity.
