Incredible fuzz pedal hand built in New Zealand in May 2026 with BC108 silicon transistors and a boost function. This is a Mk 1.6-style fuzz with original packaging, custom bag, and certificate of authenticity.

Description from Cunningham Amplifiers:

This listing of the Dual Range Fuzz is the Silicon version featuring a first-class pair of NOS Silicon transistors:

BC108 Silicon (med gain) – wonderful transistors and our go to selection classic Silicon fuzz tones.  Bright chiming cleanup, big fat tones when dimed.

The Dual Range Fuzz is hand crafted effect pedal based on our MK 1.6 Fuzz circuit. The Dual Range Fuzz takes performance to a new level by adding an additional boosted fuzz mode that can be fine-tuned for extra gain and volume. All transistors are high quality NOS devices, hand selected and tested in each circuit.

The controls are simple but highly effective - 'Attack' dials up the fuzz and 'Level' sets the overall output of the effect, which ranges from soft to sonic destruction. The Boost controls interact with the standard Attack and Level controls to provide an extremely diverse palette of tones, ranging from boosted cleans to searing fuzzed out mayhem. You can set the pedal up to create two quite distinct tones or maybe add just a touch of extra grunt to your rhythm tone for cranking out a lead.

The Dual Range Fuzz is designed to provide a high level of output when desired and is capable of a significant volume boost - this fuzz will not disappear in the mix when engaged.

There's also a little Boost Low Cut switch which shaves off bottom end when in Boost mode and the Gain is fully cranked. Switch in the up position gives you full range fuzz, switched in the down position reduces bass response to give you extra cut in the mix.

Raising the level also hits the input of your amp harder and interacts with tube preamp stages to produce beautiful overtones and a wide range of overdrive and distortion tones through to raging fuzz. Subtle changes in pick attack and tweaks to your guitar's volume and tone controls offer up unlimited avenues for expression.

The circuit is built upon a custom-made board with the highest quality components and an obsessive attention to detail. The Dual Range Fuzz is both battery powered and includes a DC power socket (standard centre negative, 2.1mm plug). The battery is disconnected from the circuit when DC plug inserted so you can leave hooked up on your board.

​Each Pedal is built by hand, one at a time, and individually voiced to optimize its specially selected pair of transistors. This means no two pedals are exactly the same - they all have unique attributes and components are chosen to enhance the sonic qualities of each circuit.
