For reals tho Rob, blend knobs are kinda niche on guitars for a reason. You really need to have the right pickup set to even notice significant difference between the three main settings. And even if you can, are you really going to sit and fiddle with your guitar that much to get it just right instead of just playing it?
Volume and three way switch probably makes the most sense.
If you don't like the harshness between settings then maybe do a blend and three way switch instead like in my video.
If you don't need volume control but only need a way to turn your guitar off, get one of those cables with the built in switch, or use a tuner pedal. Or better yet, use a volume pedal.
Two ways of doing this with a single knob. One is to use a ganged pot, log/antilog or audio taper/reverse audio taper. Don't know whether you have the depth in the body cavity to do this. To avoid re-inventing the wheel, look at this article: http://www.harmonycentral.com/articles ... r-rewiring
The other is a passive pan control circuit which will give you a minimum of 6dB signal loss and is seldom used without a booster stage to restore the signal level. It's along these lines.. http://web.archive.org/web/20060209210 ... h6_2_1.gif

Yah thats the panpot part, but rob wants an imaginary dual gang pan pot with an "intention sensor" that knows to go louder and quieter where he likes.

Ah, I forgot that he wants it to spin round and round forever, too. In that case my solution is a rotary optical encoder and an ARM board with a DSP. Programming it is left as an exercise for the student.
