Used EXPRESSO FUZZ BENDER MK I.V Distortion Pedal

Used Expresso FX Fuzz Bender MK I.V

Overview

The Expresso FX Fuzz Bender MK I.V is a handbuilt boutique fuzz pedal made in the UK, inspired by the legendary Tone Bender MK IV circuit. This particular unit is Serial #16 and was built in December 2021, featuring a genuine Mullard OC75 germanium transistor — a highly desirable component known for its warm, rich, and harmonically complex fuzz tones.

The MK I.V design bridges classic British fuzz and early overdrive territory, delivering excellent touch sensitivity and dynamic clean-up when rolling back your guitar’s volume. From gritty edge-of-breakup textures to thick, saturated vintage fuzz, this pedal covers a wide range of expressive tones while retaining clarity and character.

Internally, the pedal is neatly handwired with quality components and housed in a rugged enclosure finished in a distinctive gold crackle texture. This is an excellent option for players chasing authentic vintage fuzz tones or collectors looking for a well-documented boutique build.
