To be honest, the sets I get from planet Tone are pretty darn dynamic, and I really use picking to control volume. I have a set coming for these with a brass cover I will try to age. I generally would have at least a volume and a 3 way, i can always roll down on vol if a sweeter sound is needed, but I am trying to think of ideas to only have one knob on the top. Maybe hidden switches elsewhere or roller pots. Hm.....
You could do a concentric pot, just an idea that popped into my brain. That's what I did on my Viper to get vol/tone vol/tone out of two holes since the control cavity was just too tight. Anyways, however you slice it that thing should turn out killer!!!
I am just trying to figure out the 'blend' portion or switching between pickups. Concentric may be able to achieve a pickup blend and a volume pot. I need to get to studying up!
Now you're getting into bass wiring schematics. I don't know why the pickup blend isn't used in guitar like it is on bass. I would do a volume and a blend and call it. Blend pots are cool because of how you can mix the pickups. Then again, you can just do a stacked concentric pot and do something similar.
The blend or rotary is what I am thinking of doing at this point. I found a post online that lays out pretty much exactly what I want to do, which is turn it even more into a 3 way by essentially turning them both into 'no loads' at one end of the spectrum, meaning true neck, middle blend, bridge.
