Prism Circuits set out to create an easier way of building these vintage instruments, and to put them in the hands of the people who love to build, create, and inspire. Our goal is to make the build experience a smooth and effortless process by using quality PCB's to offer a high-end product that can stand the test of time. We love these magnificent instruments that were once dubbed the people's synthesizer.

News from the Labs

  • Prism Circuits Spring Reverb Prism Circuits  Apr 3rd, 08:04
    The Serge Modular Spring Reverb has been released and is up for sale in DIY. www.prismcircuits.net 
  • Prism Circuits Random Voltage Generator Prism Circuits  Jan 25th, 05:10
    Prism Circuits has just released the long awaited Random Voltage Generator! The RANDOM VOLTAGE GENERATOR produces random voltages which vary smoothly or in a stepped manner. Random timing pulses are also available. Rate of change of all outputs is voltage controllable over a wide temporal range. Noise is built into this unit and can be broken out onto its own jacks as an optional Noise Source.
