gorch Posted January 5, 2020 Posted January 5, 2020 Question for electronics experts. I have just finished the DYOC wah kit that has a few trim pots to dial in sound of taste and I'm wondering, what does the Q resistor do in the wah circuit?
killerteddybear Posted January 5, 2020 Posted January 5, 2020 My ancient brain remembers that "Q" is the width of the filter effect. High Q is a narrow filter (restricted set of frequencies passing) and low Q is a broad filter (most frequencies passing). For real excitement, put a potentiometer in place of the fixed resistor and try different settings as you rock the wah pedal.
gorch Posted January 6, 2020 Author Posted January 6, 2020 Great, thanks! For real excitement, it’s a potentiometer already. It’ll need a third hand to set up while rocking though.
