I have no experience with this particular amp or cabinet. But I concur that the head is probably good sounding just low power. For the same price, you could buy the new Bassman 100T head which is the modern version of the Bassman.
Or for much less money, you can look for a silverface Bassman 100 or 135 from the 70's.
