UPDATE - Solved - Thanks for looking!
Hi all,
new member, first post.
I have a Champion 110 that has a buzz that goes away if I touch any of the amp jacks.
grounding problem, right? Any suggestions on a permanent fix?
I'm a hobby guitarist and I know this is not much of an amp, but it sounds awesome and it's more then enough for me so any suggestions appreciated

How much of a buzz? Only noticeable when you're not playing guitar, or can it be heard even when you are playing?
Is your guitar grounded? Buzz normally reduces when you touch the strings or amp metalwork.
Is your house line supply properly grounded?

If the amp buzzes with nothing "plugged in" it may be a faulty shorting jack (input jack).

Thanks for the replies!
The grounding in my jam space is good, and the problem persists when I bring the amp home. The buzz is only a problem when I'm not playing.
I think it may be a bad jack as sometimes I need to fiddle with the patch cord to get it to get the foot switch to work.
I'm going to try and find some replacement amp jacks and see if that helps.

Fender Champion 110. In post #1 =0)
Could be due to a bad shorting jack on the inpot (you can test this with a meter). Could be due to an ungrounded shielded cable from the input jack to the first pre-amp stage...
Has it always done this? Or is this something that developed?

Problem Solved!
I was at my local electronics store today looking to see if I could find replacement amp jacks and since they didn't have any I figured I'd try replacing the 3 prong wall plug and now the buzz is gone.
The amp was handed down to me and always had the buzz, I guess somewhere along the line before I got it the prong for the ground was snapped off and shoved back in.
Thanks for all the responses!
