LFO-WAH

[ppaappoo]

Hi there, like beavisaudio said "Fun with the Colorsound Inductorless Wah" so lets fun!

I want to make the Inductorless Wah with the LFO from http://www.beavisaudio.com/Projects/ColorsoundWah/index.htm but i like use a triangle wave gen for a softless effect acction.

This is the eagle scheme:



The circuit have:
Volume control, speed control, depth control (deth label in the scheme) and a wave sw to select between square and triangle

I like to add a blend control too but i don't now how, maybe a 100nf in series with a pot between the input and output.

What do you think about the project?

One way to get some unmodulated signal in there would be to but a small "bias" on the LED so that it never turns off all the way. Compare with the LFO arrangement in my Trem:

The Bias pot sets the operating point of the driver transistor for the LED. I'm sure that something similar can be done with the Beavis circuit. Time to take out the breadboard...
