Formula B Pedals | Boost Guitar Pedals

Formula B

Formula B pedals are handbuilt by Marco Bovelli in Todi in Umbria, Italy. We are delighted that the Formula B range is exclusive to Boost Guitar Pedals in the UK!

Taking classic gear as inspiration, he crafts extraordinary guitar pedals with innovative features: for example, his Fuzz Rangers and Super Plexi pedals allow the user to set the boost before or after the main effect for varying sonic possibilities.

His Vintage Vibe is an homage to the Uni-Vibe, and features the lush, organic chewiness of the original, with additional features for the modern pedalboard.

FORMULA B Vintage Vibe Mk2

£199.00

So Addictive!

The Formula B Vintage Vibe Mk2 is a superb homage to the original 'Leslie-in-a-pedal', the Uni-Vibe. It's one of those memorable and highly addictive effects, up there with fuzz in terms of the character it endows songs with. 

Most famously used by Jimi Hendrix during his Woodstock set and live Band Of Gypsys album, as well as by David Gilmour on Pink Floyd tracks such as 'Breathe', and Robin Trower on his Bridge Of Sighs album, the Uni-Vibe is all over late-1960s and early '70s rock.

The Formula B Vintage Vibe Mk2 sounds phenomenal with its fully discrete, analogue signal path. Made with original THT BC549 and 2Sc1815 transistors and quality photoresistors, plus an internal voltage doubler giving 18V of power, this is capable of achieving seriously chewy, organic chorus and vibrato effects with plenty of headroom.

Like the original, the Vintage Vibe Mk2 has a Volume control that allows you to achieve unity gain with the rest of your setup. You can even use it to boost your amp or other pedals - there's plenty of volume gain on tap.

Chorus/Vibrato toggle

With the toggle in the Chorus position you get the full Uni-Vibe experience. With the toggle in the Vibrato position you get out of tune pitch-bend vibrato.

Dual footswitch

The dual-footswitch design allows you to set Speed 1 and Speed 2 and access them on-the-fly. A typical setup would be to use a slower speed for rhythm playing then kick in a faster speed for solos.

Features:

  • Analogue chorus/vibrato based on the Uni-Vibe
  • Dual-speed operation with two separate footswitches
  • Old-stock transistors and high quality photoresistors
  • 9V to 18V internal voltage doubler
  • Power: 9V power adaptor, centre-negative (not included)
  • Current draw: 100-150mA

FORMULA B Fuzz Rangers

£175.00

Legendary Boost & Fuzz In One Pedal!

The Formula B Fuzz Rangers takes two iconic circuits and encloses them in a beautifully finished chassis, with vintage-style controls. With the option to run the Fuzz or Boost independently, it's an incredibly flexible pedal for your pedalboard, but where it gets interesting is that there's a toggle to set the direction of the signal. You can choose whether to run the Boost into the Fuzz, or vice-versa. The results differ dramatically...

Fuzz

The Fuzz circuit is based on the silicon Fuzz Face, using a pair of NOS military-spec BC108 transistors and carbon-layer resistors. It sounds great on its own, and reacts really nicely to your guitar's volume pot - as Fuzz Faces do. Running the Fuzz into the Boost gets you a clearer tone with plenty of gain to push your amp, showcasing all that lovely Fuzz Face breakup.

Boost

The Boost circuit is based on the Dallas Rangemaster Treble Booster, with silicon BC549 transistors to reduce compatibility problems (polarity, power etc) with the Fuzz circuit. Uniquely, there's a toggle switch to shift the Boost emphasis between Low, Mid and High frequencies, making it more flexible than a traditional Rangemaster. Running the Boost into the Fuzz saturates the input of the Fuzz Face and gets you a rich, warm, super-fuzzy character which responds well to how you set the EQ toggle.

More than simply for fans of Jimi Hendrix and Stevie Ray Vaughan, this pedal will serve you well with its vintage vibe and tonal flexibility.

Features:

  • Dual-channel pedal with independent Fuzz and Boost circuits.
  • NOS BC108 transistors and carbon-layer resistors on the Fuzz side.
  • Silicon-based Rangemaster circuit on the Boost side for greater compatibility with the Fuzz.
  • Effects Order toggle switch enables you to run the Fuzz into the Boost, or the Boost into the Fuzz when both channels are activated.
  • EQ toggle allows you to emphasise Low, Mid or High frequencies on the Boost side.
  • Handmade in Todi, Italy
  • Fuzz, Level, Boost, EQ toggle & Effects Order toggle controls
  • Power: 9V power supply, centre-negative (not included)
  • Current draw: 10mA

FORMULA B Super Plexi V

£160.00

The Essence of the '60s...

If you hadn't guessed it already, the Formula B Super Plexi V (for "Vertical" - they also do a horizontal version) is based on the Marshall JTM45 "Plexi", with an additional Boost channel thrown in for good measure, capturing the sound of many legendary players from the 1960s onwards.

Effects Order

The Super Plexi V uses a rare Fairchild J201 MOSFET for beautifully warm, responsive tube-like tone. Like the Formula B Fuzz Rangers, there's a toggle to set whether the Boost comes before or after, giving you extra control of your sound - and more options to set your tone on fire!

Boost

The Boost channel on its own gives you plenty of gain to push your amp onto overdrive, but this pedal really comes alive when you partner it with the Plexi channel. Run the Boost before the Plexi for lovely saturation and density; run the Boost after the Plexi to increase the volume and gun your amp's power tubes.

Features:

  • Dual channel "Marshall-in-a-box" pedal with independent Boost and Plexi channels
  • Featuring a rare Fairchild J201 MOSFET for responsive tube-like tone
  • Effects Order toggle switch enables you to run the Boost into the Plexi, or the Plexi into the Boost when both channels are activated
  • Handmade in Todi, Italy
  • Level, Gain, Tone, Boost & Effects Order toggle controls
  • Power: 9V power supply, centre-negative (not included)
  • Current draw: 10mA
