Isle of Tone Haze67 V2 Fuzz

The Holy Grail of Fuzz, Refined

Joe and Steve from Isle of Tone are lifelong lovers of vintage gear. Over the years, they’ve collected, restored, and compared some of the rarest fuzz pedals ever made. That deep, hands-on experience is what led to the creation of the Haze67.

The Haze67 is Isle of Tone’s tweaked and optimized interpretation of the classic Tone Bender MK1.5 and early Fuzz Face circuits. It is not a straight clone, but a carefully refined design built to capture the best characteristics of both circuits while improving consistency, usability, and musical response.

Every Haze67 is completely handmade, matched by ear, and assembled using exceptionally rare NOS components sourced from around the world. Only the best parts make it into production, resulting in a fuzz that feels alive, expressive, and deeply responsive to a player’s touch.

The Haze67 has found its way into the hands of players such as Joey Landreth, Ariel Posen, Josh Smith, and Nick Perri.

Circuit Design and Feel

At its core, the Haze67 is based on the Tone Bender MK1.5 and early Fuzz Face topology, with carefully adjusted resistor and capacitor values. Steve developed a unique multi-stage resistor system that alters amplification rather than bias, allowing the player to move between different gain structures while preserving the circuit’s natural feel.

The result is a fuzz that behaves more like an instrument than a typical effect. It offers sparkly, glassy clean tones when rolling back the guitar’s volume control, smooth and articulate breakup for rhythm playing, and thick, saturated fuzz that remains musical and stable at higher gain settings. Throughout its range, the Haze67 is exceptionally sensitive to touch and picking dynamics.

The pedal cleans up beautifully, never collapses or sputters, and avoids the brittle or saw-like decay often associated with less refined fuzz designs.

What’s New on the Haze67 V2

The Haze67 V2 introduces several meaningful upgrades while fully preserving the original circuit philosophy and tonal character.

• New larger enclosure made locally in Bavaria, solid and heavy-duty while remaining pedalboard friendly

• Built using rare NOS yellow circuit boards sourced from a discontinued U.S. manufacturer

• On-off battery switch eliminates the need to unplug cables to preserve battery life

• Standard 9V DC power supply input

• Battery can remain installed without draining when a power supply is connected

• Front-mounted NOS USA-made “+ / –” output level switch

Output Level Switch Explained

The Haze67 V2 features a front-mounted “+ / –” output level switch designed to make the pedal easier to integrate into a wide range of rigs without altering its core tone.

In the “+” setting, the pedal delivers a hotter output level that allows it to function almost like a preamp. With the pedal set high and the amplifier’s volume reduced, players can move seamlessly from pristine clean tones to full fuzz using only the guitar’s volume control, resulting in exceptionally responsive and musical behavior.

The “–” setting lowers the overall output while preserving the same tonal character. This makes it easier to add the Haze67 into complex pedalboards or existing signal chains without needing to rebalance levels across other pedals or the amplifier.
Depending on the switch position, output levels range from near unity with the amplifier to authentic 1966–68 Fuzz Face output levels at full volume.
