So when i turn on my Roland JC-120 Head it has a hum... Its annoying. Doesnt really affect the tone but its kinda noisey.

How can i fix it?

Could something be wrong on the inside?

Could i benefit by just blasting contact cleaner in there? lol

Should i go get a really good, protected power strip?


any thoughts?

does it buzz when its powered by a battery?

swap guitar cables, try with a different guitar, move the amp to a different outlet.

Sorry peebo1845 its not a cube. Its a vintage Jazz Chorus head. lol
Alright i figured it out. Dang, kinda stupid.
So the guy i got this from pulled the ground prong out of the power supply. haha
What an idiot.
So im just gonna get a new cable, its gonna be a pain though. I have to open up the head and everything... =[

This made my day.
Everyone is entitled to an opinion.

Feel free to express yours so I can make an informed judgement about how stupid you are.
