just chords or notes? just chords seems pointless in my opinion. plus anyone who really plays the guitar will use something like guitar pro and just download free tablature - which is probably the best solution out there.

This is not solution to pro, rather to beginners. It might take a while (forever?) to find chords for not so popular song.

Chords will help you figure out the notes if you know your arpeggios and scales.

Guitar Pro tabs are user generated and vary in quality. And good luck if you want to find an obscure song.
