    Hi guys !
    I'm new on this forum so I don't know if there is already a thread on this subject (I'm a french guy so please excuse my english mistakes)... Anyway, you'll tell me :)
    I'm building my own MM like bass with a status graphite neck. At first, the electronic was a simple "volume-volume-tone" one as I wanted to keep it simple in a kind of jazz bass way. I'm not completely satisfied with it so I'd like to replace one of the volume pot with a 4 way 3 pole rotary switch.
    There are few proper informations on the forums about that kind of wiring. My goal is to be able to switch between front PU-parallel-series-back PU. I drew this :

    Do you think this wiring is ok ?

    thanks for this quick answer but it's not a rotary switch... I found lots of these diagrams but not one with a rotary switch...
    If there is something wrong on the picture, please make corrections on the pic, it'll be more useful for me.
     
  4. The diagram I posted is indeed for a rotary switch. You can cross-reference the pin layout with what you have.

    As far as I understand (not much, indeed), there is 2 problems with my volume pot.
    - The output from rotary switch should go to the volume pot and then to the tone pot.
    - The third "connection" of the pot (wich I erased on my drawing) should be connected to the back of the pot.
    Except from that, what's wrong (I'm a beginner)))) ?

  7. You didn't make any changes to the volume/tone wiring with your revision. The electrical function remains the same.

    The third terminal of the volume pot does need to be grounded.

    I drew a junction (wire) between the third terminal of the volume pot and the back of the pot. Isn't it what is needed to ground it ?

    I had a little help in an other forum (a french one) and I finally came to this :
    1- Neck
    2- Neck + bridge in parallel
    3- Bridge
    4- Neck + bridge in series

    What do you think about that ? Better than the previous one ?

    An other wiring diagram. This time, it's not neck/parallel/bridge/series but neck/parallel/series/bridge. Maybe it seems more natural to some of us than the previous one.
