The classic 4x10 Bassman - the one you can buy today as the '59 Reissue, with Jensen speakers) is a lot of people's favourite amp, and for good reason. It ranks up there with the Fender twin, AC30 with Alnico Blues and few others as a truly legandary amp. Jim Marshall based his first amps on the Bassman, and look how well they caught on. A Strat or Tele through a Bassman = guitar perfection. having cracked open both my Bassman and Marshall JTM45, I can attest to the eerie similarities between the two.
