What I noticed with the Brown setting is it's smart to back off the gain a bit as well as the treble knob. Can get really fizzy quite fast.
Throwing a low gain Blues Driver (in the boost section) in front of that for leads is fun.
Almost every modeling amp/multi-pedal I've ever messed with had far too gain in the higher gain presets. To get better sounds, I almost always reduce the gain and increase the output to compensate. Even the early Line 6 stuff I had in the mid-2000s sounded much better and more natural with about 20-25% less gain across the board.
