Re: Harmonic Tremolo in a pedal?

steveRRe: Harmonic Tremolo in a pedal?
I used a 3 meg ra pot for rate and built a 10M Ra "pot" from single pole 12 position rotary switch.  
 
I simulated the taper using 820K, 1M, and 2.2M resistors between each of the switch contacts. The first and last contact point are essentially the outer two lugs of the potentiometer and the center contact is akin to the wiper. I obviously don't get the infinite resolution that a continuous pot would have but eleven positions seems to be fine enough. (The most ccw position is off) It might be different if it was a rate control, but since it's for depth I haven't yet said, "I wish I could get right in between these two settings."  
 
I had also found a 10meg s-taper pot in an electronics surplus shop, but didn't like the taper so I went back to the switch.  
 
hope this might help some
