For the curious...
I contacted Fire Eye Development and they encouraged me to send my Twin back to them for the mod that will power the electret mic inside my guitar. Considering the cost of two-way shipping and my preferred timeframe, I decided to order a new Red Eye Twin that includes the mod. It arrived yesterday.
After trying it out briefly, I'm really excited about the results I'm hearing. This demo could be louder (sorry) but it gives you an idea of how the blended signal sounds through my ZEDi-10FX and a pair of K10's. About a minute of strumming and a little fingerstyle too.
Daren from Fire Eye has been AWESOME. Can't say enough good things about the service and communication I've gotten from him.
