there are 2 types of Chuck-A-Wahs: one using a LED and photo resistor to control the filter, the other using a FET (with high / low band switch).

The Chuck-a-Wah was made from 1975 to 1977.

An interesting device for use with electric guitars, bases, pianos and organs. The unit has a special type of sound filter triggered by the output of an instrument, the harder you play the more effect obtained.
