    T bridge->GigPro->board. Huge buzz when switch OPEN.

    Hello there,

    In my Ibanez Artcore I have an LR Baggs T Bridge, running into an LR Baggs Gig Pro preamp. I have a 1/4" jack for the acoustic side, and another separate one for the existing humbuckers. I want to keep the systems completely separate.

    However, I want to use a Strat style 5 way switch(which is really a 3 way, 2 pole) to switch between the humbuckers and the T bridge. The humbuckers are on one side of the switch, and the T bridge is on the other. I simply have the two wires from the T Bridge volume control interrupted on their way to the 1/4" jack, and attached to the last two pins of the switch.

    When the T bridge is closed-in operation-it sounds fantastic, with no noise, or hum at all. But When the switch for the T bridge is OPEN, it makes a horrendous, distorted, buzzing sound that is so hot it pins the meters all the way. It's certainly not like any 60 cycle hum I've ever heard. I have tried it on 2 different systems and the results are identical. What am I doing wrong and how can I correct this?

    Thank you for your time.
