playin through a hot rod deluxe..just retubed. sounds good except there's a jingling/rattling sound when i play bassy notes. it sounds like something rattling around in the tubes but i checked them and they're all fine (nothing loose in them). i bought new tubes for the whole thing. i'm not sure if the sound was there before i retubed. if it were a tube issue, i believe something would sound off with my tone. i'm having no such issues though, just the rattling. thoughts?
