Formula B Vintage Vibe MKII

Formula B Vintage Vibe MkII – Analog Uni-Vibe “Leslie-in-a-pedal” with dual-speed switching

Chorus/Vibrato · Internal 9V→18V doubler · THT parts + selected photoresistors · Dual-speed footswitch · Top jacks · Handmade in Todi (Italy)

The Formula B Vintage Vibe MkII is a top-tier tribute to the legendary Uni-Vibe, delivering that unmistakable “Leslie-in-a-pedal” swirl associated with Hendrix, Gilmour, or SRV—now refined for modern performance and precision, and handcrafted in Italy.

It’s built with high-grade THT components (including selected photoresistors) for lush, musical modulation. An internal voltage doubler converts the pedal’s 9V supply into 18V, increasing headroom and adding a richer, more open feel.

MkII brings practical upgrades for live use: a dedicated bypass LED above the left footswitch, a larger centered tempo LED that remains visible even when bypassed, a textured matt black finish, and top-mounted jacks for pedalboard-friendly routing.
