    I have no idea what kind of signal to give this unit to get it to
    switch. Im sure it will be an easy answer for any electronics
    professional out there.

    Its a guitar preamp (carvin Quad X), with old style 'midi' input jack
    plugs

    Here is the relevant part of the schematics:

    and

    the whole schematic is

    Your help will really be appreciated.

    Any advice?
     
  2. Any logic signal that swings about the amplitude of the V+ supply
    should work. I would probably try a 4000 series CMOS gate or buffer.
    What is the V+ voltage?
