    It appears that the Lehle switchers (dual in particular) don't have ground lifts. Are they silent from loops and hums from the iso transformers alone? Or do they need a ground lift?

    If I remember my Lehle has ground on only one channel, channel "b" I think.

    (Or at least that's what my tech told me one time. If I run only one channel it's that channel.)

    Thanks, I plan on running a clean, dirty ABY. I'll usually be playing just one amp at a time.

    Hi Rastaman,

    I f you want to toggle between your amps and not run both amps simultaneously you could use a Little Lehle. This Switcher switches apart from the signal also the grounds of both amps. Through this feature you can't get any hum-loop.
    To ABY (Y- stands normally for both amps simultaneously) your amps you can use the Little Dual or the Dual SGoS which have both now a phase-reverse and a ground switches.
    Only the old style Dual has a ground switch which is located inside the box. You have to open the top to switch it.

    All the best
    Burkhard

    Thanks Burkhard,

    I do plan on running 2 at the same time, I haven't had any issues yet but it's good to know there is a switch inside (I do have the older version).
