I have a CD (cash deposit) that just expired recently. I also have an opportunity to purchase a vintage Ampeg SVT 8x10 stack in good working order (early 70s model), appears to be all original, for a decent price. Should I renew the CD with interest rates as lousy as they are right now, or purchase the Ampeg and hope the value will rise if I properly maintain it? It probably won't get alot of live use as I can't see hauling this monster around. Probably just use it as a "practice" amp!
