I'm good with 6dB max. boost/cut even for tracking... I figure beyond, I need to do something else!

The beauty of this circuit is that a single resistor ladder determines the steps so, if we use 11 steps each way, we can set them up any way we like. So for example we could have:

0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0 ( or 4.0, 5.0, 6.0 at the end)

or

0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 6.0, 8.0, 10,0

or

0.0, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, 6.0, 8.0, 10.0 (or 7.0, 8.0 at the end)

or

0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0

It is just a matter of calculating the values of the resistor ladder. All the other EQ components remain the same.
