I am about to pull the trigger on the BOM for this design to test on the breadboard but thought it might be sensible to check in advance it is worth pursuing from the more knowledgable types around here, seeing as it's an internet source...
It seems like the 'Bax' eq appears in many formats but the way I am looking for is the 6db slope where the shelving is outside the audible range, and in my research I found a plugin which sounded just the way I wanted (but I want analogue) designed by Analogue Obsession BXQ:

... the developer (who makes some pretty cool plugins) kindly advised me was based on the schmatic figure 1 here

...because I want a 3 band I was planning on building the active 3 band version on breadboard - which uses linear 100k and 500k pots which I believe I can source from Tayda with a centre detent which will fit my design (if it works out)...
