It hurts me to sell this. It truly does. I bought this guitar about 4 or 5 years ago and it is a fantastic instrument. The only reason I'm selling it is because I simply do not have time to play it and it needs to stop sitting in the case. Brian Moore makes some of the most beautiful bodies out there and this is no exception. The i2.13 includes 3 separate outputs for your sound. There is the standard electric signal, a RMC Piezo signal (for a warm acoustic tone) and a 13-pin RMC system for synth tracking. I used this guitar many times while playing through both my electric amp and a synth at the same time. It allows for overlaying of strings, piano etc while you play a single instrument. It is a great feature for a small group in need of a fuller sound without a keyboardist.
