The Slightly Nasty Model 1011 is a voltage controlled oscillator that’s a little bit different. Despite featuring a host of functionality including four mixable waveshapes, suboctave, linear and logarithmic FM, pulse width modulation, and oscillator sync, inside it you won’t find a single IC opamp or OTA. What you will find is no less than 41 discrete transistors flying in close formation, doing their best to output useable musical tones.

The Model 1011 has been designed from the ground up to use modern “jellybean” components that can be cheaply and easily obtained from most electronics suppliers. Despite the unusual implementation, the architecture is actually a very traditional sawtooth-core design that will be familiar to most people who have worked on VCOs before.

Three outputs provide mixable sine-triangle, saw-pulse-suboctave, and suboctave square respectively, the pulse wave also featuring both manual and CV-controlled symmetry (pulse width). Aside from the usual 1V/Octave input, there are also separate inputs for both linear and logarithmic FM, each with input attenuators, as well as a hard sync input. The exponential converter is temperature compensated for better thermal stability and the sawtooth core features high-frequency compensation for better pitch tracking.

The Model 1011 uses the Loudest Warning 4U format for the front panel, and follows Eurorack electrical and power standards. All front panel components are PCB mounted for easy wiring-free construction. The front panel is available in two finishes – satin anodised and gloss white powdercoat.
