The FX unit can be found along the bottom edge of The Prince's interface.

It features five FX modules:

Noise

Distortion

Chorus

Delay

Reverb

Each FX module has a dry - wet signal dial to control the balance of dry and FX signal, and a bypass button to disable it and allow the signal to pass through unaffected.

You can also find extra parameters specific to each effect, by clicking the + button to the top-right of each dry - wet dial. These allow you to control various elements of each effect to tailor your sound.

The noise and distortion modules contain a range of different types - try distortion #4 to add some gnarly overdrive, or noise #3 for some organic aquatic ambience.
