Feedback in Left Channel when adjusting volume.

[Aaroncanderson44]

Hey all!
I finished my crack build last night (stock, I haven't installed the speedball upgrade yet). Everything sounds fantastic besides one little caveat. Everytime I try to adjust the volume on the bottlehead crack, I get a loud hum coming out of the left channel. The sound is similar to the feedback you'd hear on a guitar amp. Any idea what would be causing this, and is there a fix for it? Thanks in advance!

I forgot to specify. I have already checked all of my other equipment to make sure the sound wasn't coming from that, and it is indeed coming from the bottlehead crack.

Start by reflowing the connections of the black wires to the volume pot.
