Is it just me or is the X1's Jazz Guitar sound really terrible?

I love my X1 to death, and although I've tried editing the Jazz Guitar voice, I just can't get it to produce that soft, muted sound which is so typical of a top quality semi-acoustic jazz guitar.

I have an old Roland E-15 stacked above my Ketron which I use for piano sounds, and the jazz guitar sound on this keyboard is excellent.

Why does Ketron insist on having a raw, twangy and (IMHO) completely unrealistic jazz guitar?
