VOX Fuzz VFZ-1 Iconic 60s fuzz, reborn for modern players. Few effects have defined the sound of electric guitar quite like fuzz. The VFZ-1 celebrates this legacy by revisiting one of the most influential fuzz circuits of all time: the classic two-transistor design of the late 60s commonly known as the Mk 1.5, whose expressive breakup inspired a generation of players. Classic Germanium Character; Modern Silicon Stability Vintage fuzz boxes are beloved for their warm, harmonically rich distortion, but their Germanium transistors present familiar issues: temperature drift, inconsistent performance, and high noise. While Silicon solves these problems, it rarely recreates the musical sweetness of Germanium, until now. After extensive analysis of prized vintage units, VOX engineers developed a Silicon-based design that retains the magic of those originals. Each of the two Silicon transistors is biased at a precisely calculated operating point, allowing them to interact in the same musical, interdependent way as the best Mk 1.5 circuits. The result is a fuzz that is aggressive, yet refined, dynamic yet stable, combining timeless tone with modern reliability and exceptionally low noise. Key Features Vintage two-transistor fuzz design updated with modern stability Silicon transistors voiced for authentic Germanium-like tone and response Precisely targeted biasing for an expanded sweet spot and natural cleanup Two premium Silicon transistors Crunch Switch for lower-gain, volume-rolled-back overdrive tones Bass Cut and Tone Cut controls for wide-ranging tonal shaping High input impedance allows placement anywhere in your signal chain, even after Wah pedals or buffers Exceptionally low noise performance Compact, rugged, vintage-style enclosure Modern 9V pedalboard-friendly power compatibility The Sound of Classic Fuzz and More The VFZ-1's carefully biased first transistor offers unusually high input impedance for a vintage-style fuzz, preserving your guitar's natural harmonics and enabling full compatibility with buffered pedals and Wahs. This solves a major limitation of classic fuzz designs and makes the VFZ-1 dramatically more flexible on modern boards. The second transistor shapes the fuzz's breakup character, recreating the smooth compression and rich overtone saturation reminiscent of an overdriven vintage valve amp. Together, the two stages deliver an expressive, musical fuzz with excellent cleanup and touch sensitivity. Shape Your Fuzz. Shape Your Voice. Once you've set the amount of fuzz via the main Fuzz control, the VFZ-1 offers expanded tonal tools designed for modern players: Bass Cut: Adjusts how much low end enters the gain stages. Perfect for humbuckers, neck pickups, or tightening up the fuzz for rhythm work. Tone Cut: Rolls off high frequencies at the output, great for smoothing harshness or dialing in the iconic "violin" tone. Crunch Switch: Instantly produces the classic low-gain overdrive tones that vintage fuzzes create when the guitar's volume is rolled back, without touching your guitar's controls. Tradition, Perfected Inspired by the classic Mk 1.5 and early two-transistor fuzzes, the VFZ-1 captures their liquid sustain, mid-rich presence, and dynamic feel but with lower noise, rock-solid stability, and greater flexibility. It delivers the organic breakup that made early fuzz tones so captivating while solving the usability issues that limited original units. Legendary Fuzz Within Reach Authentic Mk 1.5 fuzz tones have become rare, expensive, and inconsistent. The VFZ-1 brings that unmistakable character to today's players with modern enhancements that make it easier to integrate, easier to control, and far more reliable without sacrificing the soul of the originals.
