Welcome. Never seen any SF bass schematics except a pre-boost switch SF II and that did not have any values. Hopefully someone who owns one will take some measurements from one. While waiting user fixit or twocorgis posted some "before" pics of the "coil" that was part of the "boost" circuit prior to removal. My search-fu is down at the moment.
twocorgis posted the schematic I recalled and guess what - I forgot it did have some component values.
I don't think anyone has addressed "Bisonic resistance". If I really needed to know I would ask Curtis Novak since he has done enough work to know what the variations are among originals and between the original and Fred Hammon's Dark Stars. Again someone may have posted a measurement in the context of one and two magnet variants, but it will take me a bit before I have time to search.
On a slightly different note I'm wondering why the bass boost switch was not very desirable on these Starfire basses. I just sold a 1968 Gibson EB-2 bass where this switch was more heavy duty than on the Starfire. Additionally it was a feature where the previous owner used it and actually liked it.
I am also curious as to why bass players in the 1960's liked this feature and when was it finally discontinued?
here are sound samples, before
