I too am a GA-lover. After playing virtually every other brand and shape, the Taylor GA is what a guitar should play, sound and look like for me. It's just perfect! Now onto your idea about coco and cedar. I'm contemplating my next GA BTO, and it's either going to be an engelmann/rosewood or- you guessed it - a cedar/cocobolo. Based upon the sonic qualities of these two woods, I think that they'd be a killer combination! (I've never played one, but I believe that it would be a safe bet for me.) From a visual aesthetics perspective, my imagination is running wild with great ideas on how to finish off the look!
...so should I tell you how I really feel?
