Question:
I have a Korg AX1500G that I use at church. I run the left side into the board and the right side into my amp, and use that as my monitor(there are no monitors at my church(rediculously annoying)). So the problem is I get a buzz/hum no matter what I plug into where, and I need to fix it soon, but I don't know how.
The power adapter is an AC 120V input and a DC 9V output. The positive is on the outside, negative on the inside(the little peg on the board). Does anyone know what I can do to get rid of this buzz? Thanks for all help!
PS. I plug the wall wart and my amp both into a surge protector, could that be the problem?
Answer:
whew that's a toughy....try to narrow it down....run the amp without the Ax1500, if that removes it then you have isolated that it's the effect unit. try a different guitar if you can, different amp, etc... you might want to try plugging the units direct into the wall instead of the protector just to see what happens. Is the jack on your guitar loose? That could def cause the problem. check the jacks on your fx unit, and your amp too. Cables are also a definite possibility, if you bend or jiggle them and they crackle and the hum cuts in and out then you've got a cable issue.
Answer:
I have used the EB Tech Hum Eliminators on all kinds of hum with great success.
Answer:
I've isolated that it's the effect unit. I just don't know where to go from there.

Answer:
Try taking each individual pedal out of your loop until you figure out which one/s are causing the buzz.
Also, I had the same trouble back when I had pedals and was using them at church. It actually turned out that it was the lights causing the trouble. As we turned them down, the buzz slowly went away. You might want to check for that.

You might want to check for that. he only has the KORG AX1500G in line...at least that's the impression I have.
from reading the setup, it smells like a grounding issue somewhere in the chain...it could be lights though...
does it only happen on certain pedal settings or is it there even when playing clean?
Answer:
It's there all the time. I only have the AX1500G, cause it's really all I need. I can't really use too many effects. Anyway, I'm 100% sure that it's a ground loop problem, but I'm not sure I want to pay $60 more to use the pedal correctly, when I can probably sell it for the $200 I paid for it, and for the $260, I can buy a used Boss GT-8 or POD XT Live.
