Hi guys. I'm thinking about swapping my head+cab for a portable 2x10" 400W+ combo. The combo should work well with my BEADG-tuned fiver and with my EADG-tuned acoustic. It should have enough power to get me heard at small to medium sized venues and it should manage an extra 1x15" cab if I decide to get one. I've narrowed the search down to this trio, depending how much I decide to spend.

I really can't make up my mind.. Cheers.
