Here's the values for the three gyrator circuits.

I removed each of the caps and measured them out of circuit.

Actual measured values are shown.

Here's a link to a gyrator frequency calculator:

http://www.muzique.com/lab/gyrator.htmI used the cap and resistor designators from this for the chart below, which shows min and max frequency and Q for each band.

You can use the calculator to redesign the bands if you want.

Also shown are the resistance values of the pot at different rotation points.

If you plug in the values, you can see that not much happens until after the 12:00 pot position, as noticed.

No overlap between bands, and the Q decreases as the frequency of each band increases.

Reducing the size of R1 will increase the overall frequency sweep.
