DIZ is based on the PT2399 chip and uses its extreme settings.The module was designed to create all sorts of noisy and glitchy sounds from any signal. The Input will be distorted, delayed, feedbacked or completely destroyed.The potentiometers control the settings Amount, Dizziness and Giddiness. The last one may be switched on or off via switch. Some say Dizziness controls the delay time and Giddiness the feedback. But the effect of the potentiometers depends very much on the presence of the incoming singnals. You will never be sure what happens next.
