I have been using this latest generation of amp modeling from Zoom, the new G series and MS series, since it was first released in the G3 configuration. I recently picked up a Boss GT-100 and was blown away by the quality of the effects. So I figured I would see how the amps sounded in a live setting. I brought only the new GT-100 to rehearsal and was very disappointed. Then I figured compare them to the Zoom. The results are right here in the video you decide.
Both the units are set to direct out, both running from USB into my DAW, Logic 8. Both I have tweaked, the Zoom slightly and the GT a bit more, trying to get the most realistic sound possible. We used the Fender Deluxe Reverb and the Vox AC models because I am most familiar with those amps. Owning both and using regularly. We also used some Modulated Delay for a clip also. Feel free to comment and let your opinion be heard.
