The 1960A is the top cab featuring the slightly angled front and the 1960B is the bottom cab with a straight front. The difference between the 1960A and the 1960B is simply their placement in the stack. So, what’s the difference between the two 1960’s? The Who became some of the biggest purchasers of Marshall stacks, with legendary bassist John Entwistle saying that he bought the 2 nd, 4 th, 7 th, and 8 th stacks and Pete bought every one in between. Jim went away to build his original idea and thus the Marshall stack was born. Pete’s suggestion was to simply cut the cab in half however due to the structure this was an impossible task. It only took a couple of weeks for Pete to return to the shop with his tail between his legs, stating that his roadies had found it very difficult to move the 8x12” cabinet and when he tried to help them out, he too found it almost impossible to move.

This fell on deaf ears and Pete was insistent on having his big cab. Instead he suggested a straight-fronted 4x12” cabinet that the angled 4x12” cabinet could sit atop of. Jim knew that this cabinet would be incredibly heavy and told Pete that his roadies would not be happy having to carry it from stage to stage. Pete came into Jim’s shop shortly after the release of Jim’s first 100W amps and demanded a bigger cabinet to go with it, suggesting an 8x12”.

Since Jim had released the JTM45 in 1962 customers were constantly demanding more power, with one of these vocal customers being the legendary guitarist Pete Townshend, a regular of Jim’s shop. It wasn’t until three years later in 1965 that the first Marshall stack was created.
