once again: example files

[Weinrich, 383, NL CE]

Hi,
another newbie and another question: Does anyone have example files for
guitar (classical or rock)?! This would be a great way for me to learn
programming with MusiXTex. I have found lots of classical files for
choirs, piano, organ . . . but not for guitar :-( and not for
rock-music. 
Is there another server, where MusiXTeX-files are stored and distributed
to the public domain?
I am greatful for every hint . . .
thanx
Weini
