Looking to replace my SS Fender Princeton Chorus with an old tube amp. My local shop has (still, i hope) an old 60's Silvertone 1484. Anybody have any experience with one? It looked in pretty good condition (the tolex looked fine and such) but is there anything i really need to look out for? the only experience i have with the silvertones is i know that jack white used 1485s up until this latest tour for Icky Thump (he moved up to Fender Twins). Im looking to go get it saturday for about $450 if i cant talk him down from the sticker. she pretty much looked like this.
