    Anyone have a clue about these?
    I found them in a drawer and I know I have tried using them in the 90's (or maybe 80's) .
    There are 3 small dipswitches on both pickups for different tonal variations.
    Now I'm wondering if they are passive or active. there is a red and a white cable from each pickup and a thin metallic cable that seems to be ground.
    All info about these and how to use the is greatly appreciated

    They are active pickups. The switches change the frequency response. There must be a thread where somebody once put a frequency diagram.
    I have a set of those too. I liked them a lot in my fretless bass (which is now equipped with Bartolini pickups).

    Red is for 9V, white is hot signal from pickup.

    Thanks! :)
    Great. I'll try to install them and listen to the variations.
