Walters is confused because he wants to make electronic wah, wah sound effects mechanically in his 50 year old Leslie rotating speaker, by modulating its speed with exotic waveforms.
I think he also wants to make the Leslie speaker's sound electronically.
He also wants to fix his worn out 50 year old wah, wha pedal, but its special pot isn't available so he wants to convert an ordinary pot.
It would be confusing to a nooby and to an engineer to analyse the rotating phase shifts and Doppler FM effects of a Leslie speaker, then try to make the same sound and new ones with opamp variable allpass filter circuits.
If I had a guitar then I would also try to make the sound electronically, but I would probably use DSP instead of millions of opamps.
It boggles the mind, doesn't it? :lol:
