ive already read through a bunch of threads, and seen lots of different cab configurations, but havent seen anybody who ran a bassman 1200 pro at 4 ohms through an 810e. will the 810 be able to take it? or would it be a good idea to get another cab? there is an ampeg 215 for sale near me with eminence kilomax speakers in it. would that be a necessary/good addition to this rig?
