Guitar Teacher resources

I have a few guitar teaching resources that I’d like to share..
I just came across this website – www.teachwombat.com .
For a few bucks, you can get of 100′s nicely formatted guitar
and bass sheets.  There’s some free sheets too, so check it out.

Here’s another site, that has some handy charts available – http://www.guitarteacherworld.com/Resources/

Does anyone else have any great resources for teachers?
Let me know!

Thanks,
Dave
