Re: EDP alternative to vol pedal [a DIY idea}

dont you hear the sudden change of FB in the loop afterwards?

what is so bad about it?

certainly possible, but once you start doing such effort, wouldnt it 
be smarter to use just two swiches: up/down ?

great

Could be done with 2-3 CMOS ICs. There might even be a specific IC 
doing exactly this.
They probably could be fed by the EDP through the switch line, since 
they use very little power.
A perfect student exercise :-)
