Avril has some very cool guitar. I collected pictures about 'em and uploaded for you all.

   

This is an acoustic one from the  Try To Shut Me Up tour.

You can see this guitar in a photoshoot.  Kinda retro blue. nice     =3

This black 'n' white patterned guitar is at a photoshoot for The Best Damn Thing album.  I think it's really coool.

 

These three guitar were on  The Best Damn Tour with Avril.  The first is an acoustic one and the other two are exactly same but in different colors.
