[ Absolut Terror ]
My bassist friend [Foxfire 7-String] says that "Guitar Pro kicks it's a**". I don't know how true it is because I haven't tried either.
And, he downloaded that. It's usually 20 bucks.
I can assure you that guitar Pro is Two Million times better than Power tabs.
Guitar pro does cost money but you can (ahem..) pirate it illgeally if you really want it and dont want to pay.
It has so many more benefits , trust me.. It can decrease/increase speeds for training, you can play along with drums bass guitar and hundreds of other instruments. You can easily make your own files, there is a much wider range of songs to download.
