Hi
apologies if this has been asked before!
I am trying to run my helix as a front end to 3 separate amps. But when I have them all connected I get a ground loop hum.I have to unplug all the unused cables to make it disappear.
My current setup consists of the following,
Mesa Roadster combo 4cm through effects loop 1 and 1/4 out hard panned left
Marshall Sv20 stack 4cm through effects loop 2 and 1/4 out hard panned right
fender deluxe reverb no effects loop so effects loop 3 Send into amp input
i have them al set to different presets as I only play them individually..
all amps and helix are on the same power extension.
all amps are connected with brand new planet waves American stage cables.
I don’t gig anymore so just want to be able to play any amp i want without unplugging any cables.
I was hoping someone would know any tricks as I don’t want to have to buy multiple hum eliminators and additional cabiles for 3 amps.
any help will be very much appreciated
cheers
