I've been running the 1960AV cab for the last 2 years and it sounds pretty decent. I've used it with several different heads including my Marshall JVM410, a Peavey 6505+, and Marshall JCM900. The low end response is decent and carries a lot of those low end frequencies pretty well, but retains a nice amount of the high end as well. It also has a nice mid range, and I feel that this cab reflects the mid range the best out of all the frequencies. However at the same time, I find my tone is rather thin through this cab when compared to an Orange PPC412. My conclusion would be because the Marshall cabs are built with incredibly thin woods when you compare it to the Orange cabs. So I will be looking to replace this cab
Despite the cab not being perfect, I still think they are quite decent cabs and it's been getting the job done for me.
The tolex is also of really nice quality and not fragile as all hell.
