Bought a Fender 38w amp off craigslist a week back and it has some noise/buzz...
Amp on without a cord plugged in = silent as a mouse
Amp on with a cord plugged into it, but not into a guitar = low buzz noise. If I touch the ground on the cord it goes away by about 95%.
With a cord plugged into the amp and the guitar = I get the buzz noise. If I touch the strings it pretty much goes away again. If I turn the tone all the way down it mostly goes away too.
I noticed there is no ground on the wall plug. Should this amp have a ground? I can put a new cord/plug on it I know where to ground it inside.
I also noticed the jack for the cord is pretty easy... not too snug. I may open the amp and replace the guitar jack.
I haven't opened it up yet and I will not get to it for at least a week (going on vacation). Am I on the right track, investigating the ground?

I took a few min to open up the amp and there are three wires (ground and white/black) inside... since there's no ground on the plug and the replacement I see online shows a ground on the plug, I ordered a new plug (with ground)
