I had a Bison with two switches, the Marvin type of Bison and I never could work out what they did!! You certainly couldn't - or at least I couldn't - get anything like a Marvin tone out of it. So, after purchasing a Marvin, in 1968, I rewired the Bison exactly the same, using only one switch!! Bingo!!

Hi, Stuart,
Roberto Pistolesi had one of those late-model (Baldwin) Bisons in his workshop and once explained to me what the two switches did. I can't recall all the details (I wish I'd made notes), but there were various combinations of pickup not available on a Marvin or Strat, both in and out of phase.
A good way to rewire a two-switch Bison is with both switches doing the same thing in parallel. Hank had that arrangement on the black Strat after 1977, when it was fitted with single-coil pickups again. It allows easy selection of any two pickups without having to physically "hunt" for the in-between sound and with one switch in an in-between position (eg, middle and bridge) and the other in a complementary position (eg, neck), you can get all three pickups on together. Of course, as a modification, it can also be done to any single-switch guitar.
Best wishes,
JN
