The strong zero VCO Core is a 16-pin DIP IC chip replacement for the normal VCO Cores of the Furthrrrr Generator.

It replaces the chip of the carrier on the PCB. You simply need to remove the original chip and replace it with the strong zero VCO – no soldering necessary.

A jumper on the PCB lets you switch between linear and exponential FM.

The digital strong zero VCO Core lets you get clearer and more precise FM-Sounds with your Furthrrrr Generator.
