acoustic guitar+LR Baggs pick up+behringer mixer+delta 44=annoying hum.

When I touch the TRS where it goes into the guitar, the hum stops. When I touch the remote volume control on the soundhole, the hum stops. Does anyone know how to eliminate this hum?

Thank you.

There is either a grounding problem or a magnetic field in the area. Try moving to other parts of the room or lifting the 3rd pin on your AC outlets. Also see if it goes away when you turn your computer monitor off (just the monitor not the computer)

My bigger question is why on earth are you recording your guitar direct?!?!? Do you own a mic? Uless there is some very specific reason you need to record direct use a mic. I would never record a direct guitar unless it was a live album. The miced guitar will amost always work better in the mix.
 
yeah ground problem maybe...or surrounding cables creating interferance. keep electical cables and audio cables away from eachother.
 
I would recommend VERY STRONGLY against lifting the ground on your AC outlets.

It's there for YOUR protection as well as the protection of your gear.

A much better way to isolate your guitar from your AC line ground is through use a DI box with isolating transformer and a ground-lift switch.
 
Thank you all. Yes, I use three mics in addition to my pick-up and blend them all together as I prefer. The pic-up has started giving me a problem as of late, even when the mics are not in use. I will try moving things around. Thank you.
 
I had the same exact problem on two different pick up systems. I discovered that my headphones were the problem. The hum didn't occur in the monitor without use of the headphones. This doesn't solve the problem, but it might help.
 
Seeing they asked 7 years ago they've probably got it sorted by now I expect...
 
aha.. That's funny ^_^ at least he's being helpful though
 
That's what you call "feeding a dead horse".

Actually if they took the earlier advice of "Try moving to other parts of the room or lifting the 3rd pin on your AC outlets." You could be close to the truth.
