Nembrini Audio’s Clon Minotaur plugin is a completely free recreation of a mythical transparent overdrive

The plugin window may be opaque, but the brand insists the drive is transparent.

Nembrini Audio is currently giving away its Clon Minotaur plugin, a digital recreation of a certain transparent overdrive pedal – all you have to do is sign up for an account on the Nembrini site.

The plugin is described as ‘transparent,’ a term often used to describe the Klon Centaur that it emulates. This effectively means that it doesn’t alter the frequency content of a guitar tone as much as, say, a Tubescreamer-style overdrive, which adds a considerable midrange hump. Instead, the response curve remains flatter across the whole spectrum.

The clipping stage of the virtual pedal digitally models a set of germanium diodes. Like the original, the ‘gain’ control doesn’t adjust the amount of clipping but instead changes the balance between the blend of clean and clipped signals. This summed signal is then fed into the volume and tone stages.


The original Klon was designed between 1990 and 1994. Since then it has become a fabled piece of guitar gear, with prices often reaching over $3,000.
