Tone and durability are a given with Mesa, but versatility doesn't equate to practical usability. Having multiple modes is fine but if you can't footswitch between them, you have to make adjustments at the amp on stage to take advantage of them all. My TA-15 had multiple modes, but it was impractical to switch between them during songs or even between songs, especially on a dark stage without the amp at eye level. I found that as a practical matter I was limited to two modes out of five. That's better than two out of two, but not as versatile as it could be if the mode options could be selected on the fly or could be assigned to a third channel. For recording, the multiple modes, headphone out, and cab clone are undoubtedly of value, but for stage use I'd have preferred a way to access the three basic sounds needed by anyone playing a variety of rock and pop musical styles in a single gig - clean, crunch, and lead - on the fly. As is, this is like the TA-15 in that you can have any two, but not all three without resorting to an outboard pedal or to a much bigger, heavier amp than is needed under most circumstances. A two-channel amp by itself just isn't sufficiently versatile if you need to be able to move seamlessly between clean, crunch, and lead tones during a set.
