Has anyone done this? (idea for mid sweep)

[iknowjohnny]

I may be way off here, but i had an idea that seems to me like it should work. But i figured if it did someone must have done it. The idea was to take 2 different cap values for the mids in a tonestack, one that is at the very low end of the mid spectrum and one at the high end of it. Both soldered to the same place coming from the slope R and the other ends each going to one side of a linear pot with the wiper going to the mid pot. It seems like this should let you sweep the mids to find the exact mid sound you want. Am i off base here or will that work?

it wont work like you think it will although it will do stuff.

Ive used a rotary selector to do this.

Yes, and a 10k pot that you know goes to zero to ground off the pot.

Slope is simple and gets lots of action for mostly nothing in wire and parts.

bang for buck would be slope control, then a 2 pole switch with mid and treble cap combos, then the 10k mid scoop, and I can get away with a rediculous bass cap and fixed resonance, .22 and .0047 over whatever the middle of the 1MA pot I tested it with measured. If you swap the treble pot to a 1MA and put a switch on that to make it 250k or 100k then you have pretend versions of almost any tone stack and everything outside and in between for are far as the ear can hear.

I'm not really interested in a million tonal options. I would just like to be able to hone in on the perfect mid frequency. Has anyone actually tried the idea i described or are you going from theory/math?

You may find this patent application interesting:

Yeah, that IS interesting. It's not something i'd do, as it would require a rebuild of my tone stack and would likely change the entire amp more than i want. But interesting none the less.
