Tell us about yourself!
Haven't tried that, there's a bulge near the bridge which will cause trouble when tighten the strings, but I guess it'll be ok with a better shaped guitar.
No wierd resonance or "tap" you mentioned, it has a tiny electric hum when you stand very close to it though.
I'm not a hi-fi enthusiast, but I'm quite amazed by the sound it produce. It's not perfect, there's a slight electic hum when it's very quiet.
