The blue diamond tolex exterior is in near perfect condition, with very few subtle scuffs. The grille cloth retains perfect structural integrity with only slight fading. Quite simply, this amp is extremely clean, approaching near perfect. It works perfectly, and sounds amazing. There is not a single issue with this amp, and it is worthy of the finest amp collection.
All of the tubes are original and have date codes consistent with a mid-’60s production. The amp includes the original dolly, which is in comparable perfect cosmetic condition as the amp itself.
