There is some boxy and woody quality. The piezo is so buzzy though and kind of 
high pitched. I wonder if low pass filtering the synth signal would help cut 
down on the buzz. If you get better results in any future experiment, it would 
be interesting to also hear what the piezo sounds like by itself so it's easier 
to see the affect of the guitar body.

Actually that's not half but opposite.

If you ever get that done I'd be very interested in how it sounds. I searched 
around for a cello on the internet a while back and saw that they can be bought 
new for as low as $250 to $350. However I've been hesitant to spend the money 
unless I know it will produce useful results.

Much like the different pickup positions on an electric guitar. That's why it 
might be better just to mic the cello from a small distance away as you would 
with most acoustic instruments.
