Hi, I saw you own a Pignose 30/60 amp. I'm about to sell mine I don't play it enough, and I have a question. I've noticed on mine if the volume is kind of turned down you hear a clean signal then a little bit of fuzz underneath. Like two signals; a dry direct and a fuzz channel. Is this normal? This has never bothered me, but I want to make sure the amp is in tip-top shape before I sell it. Thanks!
