Not bad...but yeah, the cab will need to be a powered one if you stick with this size. Also, the output module's a couple hp wide in this. My suggestion: Ladik A-540. Also stereo to 1/4", plus you get a little level meter on there.

I still think that going to something larger, such as a Tiptop Mantis or an Arturia Rackbrute 6U, would be a good move, tho...
