Hi Lurex,
Probably there are a lot sites on the web about it,but I usually search for the songs
I'm interested once at time checkin' for name band,title song and tabs..
It's not easy to find cool things, in garage punk,but try it before..
Then I found an interesting software called -GUITAR PRO 5- It works like a mixing panel,you have the volume for each track of the song and the tabs for each instruments,very easy to use.
But you have to find the song you'd like to learn before. There are folders with 10000 songs in all the genres on the web,and lot of this are good stuff!! Just try for "Guitar Pro Tabs" and see what you find.
Good Job,FREDDI
