Yeah I read in an interview that Tre broke Mike's bass accidently on stage once, and even though he might have gotten it fixed, he stopped using it after that because Billie bought him a P-bass for his birthday and he fell in love with the sound. but your absolutely right, hes never loud enough. especially whenever they play anything off Insomniac. I think he shows a lot of his abilities on that album, the Screeching Weasel one as well. some of the other albums, I can tell he is more interested in the sound of the bass, as opposed to how he is playing it.. not that there is anything wrong with that.
