“Made in London, England in the 1970s. Very interesting wah device for use with electric guitar, bass piano and organ. The unit has a special type of filter sound triggered by the output of an instrument — the harder you play the more effect is obtained.”
- Intensity (black knob) — Controls how much the filter moves in response to the input signal.
- Switch (black small one under the on/off switch) — Switches between 2 types of filters (bandpass and lowpass) or between 2 bands (low and high)
- This type of Chuck-A-Wah is using a FET (with high/low band switch) and operates on one 9V battery
- The Chuck-a-Wah was made from 1975 to 1977
