Found a bare pcboard for a 6 band EQ at this URL.

Circuit uses thru-hole TL074 opamps, not SMD/SMT parts. I can set the band and center frequency controlled by each pot. Anything risky about this pcboard circuit?
Found this 8 band Stompbox EQ which looks promising at $30 plus
shipping.

There is an old piece of software I used to illustrate the spectrum of
an unwanted background tone I heard in my hearing aids. Runs ok on WIN XP.
Spectrogram v5.17 (294kB)is the last SHAREWARE release of this program.

At same URL see tutorial "K2 crystal Filter Alignment using Spectrogram v5.1.7" K2 is a HAM radio kit.
I will be using these EQs in two ways to steepen band skirts.
1. In series with my multiband Radio Shack EQ
OR
2. Two of these EQs pcboards in series.

I notice you mention that you are using a Radio Shack EQ (the 15 channel stereo one?) and want to put a 2nd EQ in tandem with it to achieve the slope and range you need.
Depending on the response curve you need, you might find a simple filter or a parametric equalizer would do better for this task. For example a simple buffered RC circuit has a 6 db/octave slope that is not limited in "boost/cut".
There are also very simple but flexible parametic equalizer circuits you can build that might fit the application better.
If you go the PCB EQ route, you might think about scaling the capacitors so that you have an extra band centered at 4 Khz (removing the one at 62.5 Hz).
