It's a little different with amps. Guitars are relatively easy to fake unless the perspective victim knows the details of the instrument he wants intimately. With amps, even the ones in the linked thread, if a buyer knows enough to seek out a specific model, even if it's a forgery, the amp has to be the functional equivalent and, in most cases, a similar model and vintage. In essence, the copies ARE as good as the real thing, just lacking the collector value. In that, aside from aesthetics, the people ARE getting what they pay for. I'm not condoning or advocating the practice, but it does highlight the ridiculousness of hero-worship affecting resale value. Playing through an amp that used to belong to the Ox won't make you able to play like him. ..but then again, that discussion is taking place on a
guitar forum.
