Fuzz Rangers

The Formula B Fuzz Rangers combines two legendary circuits—the Fuzz Face and the Dallas Rangemaster Treble Booster—into a single pedal, offering vintage-inspired tones with modern flexibility.

Dual Circuits

The pedal features:

• A Fuzz circuit based on the silicon Fuzz Face, using NOS military-spec BC108 transistors.
• A Boost circuit inspired by the Dallas Rangemaster Treble Booster, using BC547A transistor.

Signal Routing

With a toggle switch, you can choose to run the Boost into the Fuzz for a saturated, warm fuzz tone with midrange flavour, or the Fuzz into the Boost for a clearer, more powerful output.

Fuzz Circuit (left side)

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 genuine Fuzz Faces do.

Treble Boost Circuit (right side)

The Boost circuit is based on the Dallas Rangemaster Treble Booster, with silicon BC547A transistors to reduce compatibility problems (polarity, power etc) with the Fuzz circuit.

Uniquely, there's a toggle switch to adjust the Boost frequency cut, making it more flexible than a traditional Rangemaster:

Low Gives you a full-frequency response including the bass.

Mid Focuses on the low-mid frequencies for a vintage valve-like frequency response.

Hi Focuses on the upper frequencies for a lovely glassy sound.
