I know that the speaker cabinets got wider as the company grew, didn't the heads also get wider? I know my 361 and 371 quite well but not the newer gear.I'm not sure what you mean. the head cabs are all about the same size. The 370 I'm referring to is my other amp heads. They all sound similar. The 320 is like have 2 amps in one. It's great for switching from a mellow to grit
