So, what’s the difference between the two 1960’s?
The difference between the 1960A and the 1960B is simply their placement in the stack. The 1960A is the top cab featuring the slightly angled front and the 1960B is the bottom cab with a straight front. Depending on who you ask, people will tell you that because of these slight design differences, the cabs do sound slightly different to one another, with the 1960A being clearer and more balanced, due to the angle of the speaker being aimed more towards the players ear, while the 1960B has much more bass presence. In actual fact, while you may hear a minute difference, both cabs use the same internal parts and are built in the exact same way, so the differences between the two are almost unnoticeable, especially if they are both mic’d up.
Of course, like all Marshall products, the 1960 cabs were subject to a few experiments based on customer requests. The 1960a and b's on sale today stay true to their original sound however we do also have some of the more popular variations from over the years available as the AX/BX, AV/BV, and AHW, BHW cabs.
