    this is available on the Baritone (right?) Silhouette Bass Guitar made by Musicman!

    Now i very familiar with lever and toggle switches operating that function (series/parallel + others). but i never heard of rotary selectors! i am assuming thats the third knob on that bass!

    anyone can provide information about this?

    I don't know if this is what they use but I've used it in several guitar and basses and it's extremely versatile, plus I think an extra knob looks much better than a toggle. That particular one has four poles and can be set to two or three positions, but there are also versions with 3 poles / up to 4 positions and 2 poles / up to 6. To give you an example of what it can do, the one I have in my #1 bass (a J/MM Warmoth with a Fender Noiseless Jazz pu) does the following:

    - Position 1: Bridge pu wired in series, Neck in series
    - Position 2: Bridge in parallel, Neck in series
    - Position 3: Bridge split, Neck split (so they're hum cancelling with each other)

    I have a toggle now for active/passive, but previously I had it wired so that Position 3 was like 2 but in passive mode. If there's anything in particular you have in mind let me know and I can tell you which specific switch you need and how to wire it.

    i dont understand.

    is it completely variable or detented in 3 different positions? so you just rotate in fixed positions instead of moving a toggle?
  4. detented, it'll "snap" between each point, so it can only be at one of the few positions i think, i think it'll be kinda like the mid frequency selector i have on my SVT-II, its a knob that you can only choose 1 of 5 pre set positions with

    that could be quite nifty if its available in concentric pots when you dont want to drill new hols.
