Just a quick plug here for Tom's tube tamer. Anyone who has a peavey classic 30 or delta blues needs one of these things. The first night I had my delta blues I gigged with it and didn't notice any tube rattle, but the first practice after the gig, man I couldn't believe how much rattle noise that thing made. Anyway, got a tube tamer off of Ebay, and wow, no more rattles. Cool product Tom.
