The AC15 is 45 lbs, I believe. Mine feels that heavy, anyway. I also prefer the CC1 to the newer C1, mostly because of the speaker, I think. Mine has the Celestion Blue, but I even prefer the cheaper Wharfedale to the Greenback in that particular amp. Not that the Greenback sounds bad, it's just not my favorite in that amp. That said, the newer one does natural overdrive a little better, and I think it's because of the speaker.
