Summary

The RingFolder, from PM Foundations. This is a combination wave folder and ring modulator, with inputs for the folder (Z) and X and Y for the ring modulator.

The module takes a sine wave and can manually fold the incoming sine wave in either a soft/triangular effect or a hard/square/crunchy effect.

Electric guitars are easily within your reach with this powerful little module.

The attenuated input for folder modulation allows voltage control of the fold amount.

There is an onboard mixer, providing the ability to fold an input sine wave, the output of the ring modulator or a combination of the two.

Listen and watch the demo video which says it a lot better than these words! Thanks Randy.

IMPORTANT NOTE

This is a PCB and Panel set only. A set of 1 high quality PCB and 1 front panel ONLY are included. You will need to purchase your own components and build your own module. Comprehensive build instructions and BOMs are provided to help you source the components needed and we even provide links to shopping carts to simplify sourcing those components. Some product photos above show COMPLETED build.
