I've had one since late December 2012 and I love it. I currently have an Ashdown setup with a mag200 head and a 4x10 cab. The TC BH250 replaces my cab and I gig with it regularly! I've got 40 gigs this year with my band and I'm using it on virtually all of them, so yes it's good, yes it's bloody loud enough (even for bike rallies and pubs) and its not even turned up full.
The one issue I actually have is the Toneprint software has a tendency to lose all my bh250 settings so the guys at TC have got to fix that!
Plus, make more Switch 3's available!! I need one.
