Foot-switchable volume levels ... with a twist.

... um... maaaaaybe...

I'm not sure that I understood (still not) what g-one was talking about. I thought he meant to use a dual pot with two concentric knobs. Which didn't quite make sense to me. But a dual pot with one knob would work.

But reading Mark's reply made me realize that if I took the volume box idea and just built it into the pedal, that would be about as good as it gets. It'd go master volume -> footswitch -> second volume. The second volume would be set lower than the first. Then adjusting only the master would maintain the relationship between the two volume levels without having to touch the second volume. I can't believe I couldn't come up with that on my own. Je suis un ditz.

The proper phrase is: "Je suis une espèce de con".

I meant a dual pot with single shaft/knob, but it sounds like you have found a good solution.

For the record, a dual pot means one with two resistance sections. COncentric shafts means two shafts around the same center, in other owrds an inner and an outer shaft. Very different from a single shaft on a dual pot. In concentric shaft applications the outer shaft knob is shaped like a ring, while the inner shaft knob is conventional.

One common place to see concentric pots is on old stereo receivers, the volume control would have a ring around the outside that moved separately to control the left/right balance.

COncentric shaft implies that the two pot sections be controllable separately.
