Microvolt 3900


A Love Letter to the Analog Monosynth

We have begun shipping Microvolt 3900s, and the first run is nearly sold out. Orders will be fulfilled First In, First Out. Thank you!

The Pittsburgh Modular Microvolt 3900 is a modern, semi-modular synthesizer, inspired by the instruments designed by our heroes. The Microvolt 3900 takes a new approach to building a raw, analog monosynth with a host of unconventional and inspirational features.

Creative Synthesis Design

With our new temperature stabilized, dual VCA oscillator core, the analog audio engine of the Microvolt 3900 feeds a set of timbrel waveshapers crafted for deep harmonic shaping, enabling a layer of additive synthesis alongside the classic subtractive synthesis waveforms. Waveforms are fed into our binary filter, a custom state variable filter architecture offering near infinite resonance with or without self-oscillation. Sonically this creates a juicy, fluid filter adding depth and energy to the oscillator that can scream if you ask it to.

Microvolt 3900 Highlights

  • Voltage controlled West Coast style wavefolder.

  • Switchable harmonically rich sine wave.

  • External preamp with independent 30x gain and output level controls.

  • Classic Pittsburgh Modular low pass filter with extended resonance.

  • Dynamic VCA with standard VCA and dynamic low pass gate modes.

  • Variable overdrive on output.

  • Multi-mode sequencing arpeggiator.

  • Chaotic random CV and gate generator.

  • Multi-tasking function generator works as a voltage controlled envelope, LFO, and oscillator.

  • Highly tuned ADSR envelope generator.

  • 39-point Eurorack format compatible patch bay.
