I have tried alot of different cabs, and the Atma sounds great through most of them.
Having that said, I never did like the V30, had a Suhr 1x12 with V30, and it had a shrill sound.
For a while I ran a 2x12 with greenback and G12H30, sounded great, but I wanted something smaller.
I friend of mine suggested I try a cheap VHT special 1x12 cab with a Emminence Cannabis Rex. This cab is amazing, and sounds better then anything Ive tried.
It isn´t available anymore, but I wanted something similar to sit in our rehersal, so I ordered this:

Much cheaper then going with the Mesa or some of the other high end cabs (if you cant find the Atma cab wich just looks awsome). Check out Musikproduktiv.com I know they had the Atma cab for a while.
