Mojo Maestro Passive Clipping Colour

The Mojo Maestro is a Colour creation from Audio Expert Ethan Winer. Ethan published the Mojo Maestro circuit in AudioXPress Magazine to show that, "there’s no reason to pay thousands of dollars [...] just to get some subtle distortion." And now Ethan has graciously made his circuit available for the Colour format.

The Mojo Maestro is a tried-and-true, diode distortion circuit with several options for customization. In "Glue" mode it provides gentle saturation that can warm up sterile tracks, while "Mojo" mode pumps up the gain for intense, guitar-pedal distortion.

The clipping style can also be customized to "SYM" (symmetrical) or "ASYM" (asymmetrical). In SYM mode both clipping diodes are engaged to clip both the top and bottom of the wave. This mode generates even harmonics (2nd, 4th, etc.) and is the more aggressive of the two. In ASYM mode, one of the diodes is taken out of circuit so that only one side of waveform is clipped. This creates both odd and even harmonics, and preserves more of the integrity of the original signal than symmetrical clipping.

Besides sounding great, the Mojo Maestro makes a great sandbox in which to experiment with circuits and distortion.

Real analog plugins.

Colour is a new format for analog audio gear designed for and by the DIY community. We took our favorite sounding analog circuits and put them on modules that are small, affordable, and swappable.

The Colour format consists of Colours and Palettes:

Colours are ultra-compact, pluggable analog circuit blocks that impart various types of analog color. Check out our ever-growing selection of Colours. Colours can be designed and released by anyone.

Palettes provide controls, power, and support circuitry for Colours. We currently offer the Colour 500 Palette and CP5 Mic Preamp with Colour.
