    I am getting the very common hum when I switch to series. Everything that I have found here and on GbL says the problem is because the control cavity is not shielded. Is this something that I can do, if so how do I do it? Do I just need to take it to a guitar guru? I haven't noticed the issue that much until I changed the battery before the last gig. I hum was real noticable and I had to switch it to parallel between songs.

    Where are the G&L guys? This thing is driving me nuts.
  3. It sounds quite odd to have problems with hum that only occur in series mode.

    Are you sure it isn't a single coil mode rather than series?

    The center toggle switch is switched forward toward the neck. Shouldn't this be series?

    Yeah, toward the neck should be series on a US L2K...

    I've never gotten hum from that position on either of my L2Ks or my L2.5K... Is there not shielding paint in the control cavity?

    Some guys pull the guts out and add copper foil inside the cavities which could help, but you could have something else going on here with the pups or the circuit.

    You should really go ask the folks in the G&L forum at where most of the G&L heads hang out.
