Re: Now this is cool.. TC Electronics Mimiq Doubler..
This is a very cool premise and definitely better than the previous solutions. However, I can still hear very minor, non-mono-compatible phase discrepancies which while nowhere as bad as previous ADT technology, still isn't as good as a very tight guitar player double tracking themselves by studio standards and live, you want as coherent a signal as possible. I can see this leading to some loss of definition factoring in volume, venue acoustics and the fact that most sound guys mix in mono so nobody on either stage side misses anything which would negatively affect your sound well before anyone notices that it sounds kinda like it's studio double tracked.
Running a guitar track for pro-shot audio of your band if you're the sole guitar player so you can keep your performance authentic to what was actually played and not have to overdub a second track in the studio, but still get that studio-doubled sound is another story and this would be perfect for that.
