Katana 50 MKII : Good at everything but not great at anything.

I'll give this a 4/5 across the board. It does the job, and while it's easier to use and sounds better than some alternatives, it just doesn't sound great. At the edge of breakup it sounds a bit like the distortion is pasted onto the clean sound and high gain is fizzy. I also think it's odd that it doesn't have an FX loop along all other connections.

The value comes from the versatility and the fact that you are able to use it as an USB interface. However, I ended up with having a tube amp and a separate USB interface with VST plugins. While this does what both of my current amps do for less money, I wasn't satisfied.

Your mileage may vary but be wary! And if you can spend the additional money on the 100w version you'll get more headroom and an FX loop. I'd recommend that one over this.
