Zappa69

I'm being offered a really good deal on this model. Have you heard bad things or had bad experiences with Eden gear? I was quite impressed in the shop and have only read favourable reviews. Playing with the band might prove a different matter though. I'm sure 225w is ample (pardon the pun) for what I want, my current rig is a 150w, it's just too big, too old and too heavy. I just wanted to use the combo to drive the on-board and the additional cab to move more air at bigger gigs.

A little advice required please. My local dealer has suggested an Eden 2251 combo and having tried it I really liked it. I've read though that I can't run another cab in tandem (I intend using a 1x15" speaker cab, 4 ohm, the on-board speaker also runs on a 4 ohm load). I've just read that the amp automatically cuts the on-board speaker when you plug in and additional cab. 1. Can anyone explain why this is? I get the impedence issue but don't most other manufacturers allow external cabs in tandem to be used to move more air? 2. Is there a safe work-around?
