On Twitter, @SourceAudioFX let me know about their motion-controlled bass wah pedal. Motion-Controlled bass wah pedal?!?! Well, I surely had to check that out. I was pretty impressed with the video I saw which is included below:
Interesting to use a light source for the manipulation. Reminded me of a Theremin guitar effect pedal that you could manipulate with a laser pointer, also reminded me of my Morely Power-Fuzz Wah, which used photo resistor instead of potentiometer to ‘wah’ the tone. I thought it was interesting idea to have a ‘ring’ or you could mount it on the headstock. I’m wondering if it’s using a specific light frequency since you wouldn’t want other light sources to manipulate the effect, etc.
