The amp is a 40w Fender Blues Deluxe Reissue.
The amp is basically brand-new. Recently it started emitting a high-pitched feedback-like sound that I KNOW is coming from the amp (it still comes when the guitar's volume is down all the way. However, I think it only happens when the guitar is plugged in, but this doesn't happen with my other amp so I'm convinced that this is an amp issue.
During Thanksgiving, my relatives screwed around with the amp, plugging in the mic and my 2-year-old cousin flipping switches randomly :eek::eek::eek:
You know how hard it is to tell relative to stop messing with your "toys." I don't remember this sound coming before thanksgiving, so this relative disaster could've been it.
I need to know what's causing this please and how to fix it
I know it's been a while
Find the silver linings... eventually you'll have a small fortune
