Okay, here is the section from one of my reference books copied here word for word:

 

A linear pot is usually marked with a B or Lin and will reach 50% of its total resistance at 50% of its total rotation.  Humans do not perceive volume as a linear scale, however, so these pots sound like they are doing very little for the first three-quarters of their rotation.  Audio taper pots are usually marked with an A or Audio and have a logarithmic scale of resistance that increases volume in accordance with human hearing.

 

Moreover, all of the wiring schematics that I base my designs on always use a B pot for volume and an A pot for tone.

Try not grounding the 3rd lug on the tone pot.  I hate blend pots, way more control with a 3 way switch and 2 volume pots.  Infinitely more.  In the hand drawn sketch the tone pots don't look wired right.  Looking from the bottom it should look like this:

 

No ground on the 3rd lug and the cap from the middle lug to the back of the pot to ground.  I use audio taper pots.

Try using 2 A pots instead of an A and B pot Wes.

B pots are linear and and give the impression of nothing happening for most of the rotation.

Right. Hmmmm. I think its a wiring issue rather than a pot issue.

Yup. Had it that way originally.

 

Ehhhh, well, a 3-way only has three selections per se -- neck/neck-bridge/bridge. The switches I have can control not only each pup, but if its single, off, or dual coil.I just can't find a good single switch to control each pup individually.

 

Now, what I REALLY need is a true blend pot.

I think I bought a set of four 500K pots with two As and two Bs. I _think_ I am using the B pots as the volume and blend. A pots as tone. I _think_.
