For all the benefits of modeling devices—and I have been an early and fervent adopter—I sometimes struggle with the perception that they just don’t sound like “an amp in the room.” Well, I A/B’ed the full-range GM-Io sound with a powered Kemper driving a 2x12 cab and I was super pleased with how it matched up. Players will split hairs forevermore about these points (as well they should), but the GM-Io absolutely passes my real-world test of “Does it sound like an amp and feel like an amp?” Yes it does, in a beautiful fashion. Forget what you think you know about powered wedges, running direct, and all that, and give this thing a listen. It is a hip, sweet-sounding solution to the digital conundrum in a great-looking compact package. Nicely done.
