I'm sure there are tons of guitar players using GP out there. They just released new version of this ultimate tabbing program at http://www.guitar-pro.com/en/index.php?pg=product. You can download a 15 day demo. It seems quite much like GP 4 at first try. Does anyone know what's new in it? It seems it still has 16 channels. I would have liked to see some since I always run out of channels in my overlayered songw. But atleast the notes can now be seen alot better.
