Warwick Thumb MEC Pre- parallel or series?

    I can't tell from looking at the circuit, since it uses little PCBs, but is the MEC Pre wired in parallel or in series?

    When the blend is in the middle, the output is much louder than either pickup by itself, and the character changes a lot (sounds more like a P than a J). Am I hearing a series connection?

    Thanks in advance,

    It's wired in parallel.
    If it were wired in series, there'd be no need/use for a blend knob.
    For example, taking two single coil pickups in parallel and running them in series gives you ONE pickup with two coils. So, there's only one signal to control the volume of, and so nothing to blend.

    Well, I didn't know if they had some way complicated circuit there or not.

    I guess they have some kind of "constant volume" thing on the blend control that isn't working quite right.

    With a blend knob, you have two inputs - neck hot and bridge hot.
    The parallel / series operation has to take place before the blend pot in the signal chain. When in series, you only have one 'hot' signal.
    I can't think of anyway you could do that post the blend pot.
