I've been toying with the idea of using pedals with my Katana Artist for a while, or at least trying them for comparison. Today, on a rainy day here in Vancouver, I decided to take my unused MD-500 (I've decided I'm not much of a modulation guy) into my local store and traded it for the AT+. Sounds: So far, I'm digging it: I created a simple clean setup on the Kat and plugged the AT straight in front. With the boost, I can get into pretty high gain territory, but it also sounds good dialled back with the guitar volume. The boost on its own is a nice touch and allows another option when looking for a cleaner tone that still breaks up, without engaging the primary gain on the pedal (the 2 foot switches are completely independent). Convenience: Perhaps more important than the sound is I am liking the convenience of just stooping down to adjust something. Don't get me wrong, I'm not a Katana hater by any means, but I'm also not much of a menu diver (I use enough IT at work), so just using the Kat like an ordinary amp and adjusting settings on the pedal is much more my style.
