The Malekko Heavy Industries Diabolik is a fuzz pedal built on the company's own B:Assmaster circuit, a design aimed at players who want fuzz that keeps the low end intact. Pedal of the Day's reviewer called it "one of the most adaptive fuzzes on the market"1. It sits in the wider family of fuzz pedals, and Premier Guitar reviewed it as a bass fuzz2.

What it does

The Diabolik is a harmonic analog fuzz derived from the B:Assmaster circuit, which Malekko also offers as its own pedal1. Two of its controls, Fuzz and Clean, are "developed straight from the original circuit," according to Pedal of the Day's review1. The Fuzz control adjusts the level of just the fuzz signal, with no effect on the clean signal, which the reviewer noted is useful for blending1.

What reviewers said

Pedal of the Day's reviewer highlighted the pedal's low-end response: "My favorite feature, however, is the fact that it allows a lot of low-end to pass through!"1 That trait is a large part of its appeal for bass players, and Premier Guitar reviewed the pedal in that context as the Diabolik Bass Fuzz2.

Premier Guitar's reviewer also noted the pedal's size and build: "the rugged blue and pink chassis doesn't take up much more space than a bar of soap"2. RockBoard's PedalPedia likewise lists the pedal as a Malekko product3.

The B:Assmaster connection

The Diabolik's circuit comes from the B:Assmaster, a harmonic fuzz design from Malekko Heavy Industry that Delicious Audio describes as a hand-built pedal4. Players who want the original circuit can look at the B:Assmaster itself, while the Diabolik carries that design into a compact enclosure1.
