First time I've used it with people in a real-world situation; drummer, two electric guitars, bass, and a miked (well, DI into the PA) acoustic guitar. Not John Bonham on drums. The Katana was more than loud enough; the other guitar player was using a Deluxe Reverb, and I could have buried him if I had been rude. As I expected, using anything but the simplest of the effects is kind of problematic with the Katana, which IMO is not great when it comes to ergonomics and effects even though the effects themselves are mostly good. Reverb at least is a snap because there's only one knob and it's also the on/off switch. I don't have any foot switches for this. I ended up using my Zoom G2 pedal in front of the amp because it's so much easier than messing with the Katana, and because it actually has a pretty good tuner in it while the Katana doesn't have one of any kind. Overall, I was pleased with the amp; the sound was fine when I had it adjusted right, and the volume is there. A REALLY loud drummer would need something stronger to keep up, I think, but you're not going to find somebody who plays like that in a small venue for obvious reasons. It's hard to beat it at a typical price of $200 for a combo amp that can gig and sound decent.
