Question on Les Paul Volume Controls

    Hello,

    I recently purchased a new Les Paul Studio and noticed an odd behavior
    between the 3 position selector switch and the volume knobs.

    I'm new to electric guitar so I don't know if this is normal, but I don't
    think so. When I have the selector set to rhythm, the rhythm volume works
    and the dame for the other setting.

    When I have the selection switch set to the middle position I expect to have
    both knobs active so as to be able to blend the sound from the two pickups.

    This is not the case. Sometimes they both work and sometimes only one, and
    sometimes neither.

    Nothing seems to be repeatable. This usually happens when I turn the volume
    controls down to zero and then turn the switch and then turn the volume back
    up.

    I'd simply think it was a problem with this guitar, but a friend has a LP
    standard (2003) and it does the same thing.

    Ever heard of this?

    Thanks!

    Gary

    Not odd - normal. On a Les Paul turning either volume knob to zero will give
    overall zero output in the middle switch position. It's because the controls
    are not isolated from each other which AFAIK would be impossible in a
    passive/mono setup.

    Normal wiring for a Gibson.
    If you can read a schematic look here,

    http://www.guitarelectronics.com/diagrams/universal/hh2.html

    You want the pickup lead on the middle leg of the pot and output
    going to the 3-way switch. The schematic shows you the wiring
    the way you'll view it when you're looking at it.

    This should not happen.
    Have the selector switch checked.

    This is normal with stock LP's, 335's etc. When both pickups are
    selected, the pickups and their respective volume controls are in
    parallel and tend to interact with and shunt each other out when
    rolled off.
