I honestly never use this site to learn songs. Whenever I want to learn a song I just find the most accurate tab out there and I listen to the song. So if any of you still want to learn some Hendrix songs, Tab Pro has some of the best tabs for ALL of his songs. I think it's like 4 bucks to sign up for the full version of Tab Pro for an entire YEAR. Tab Pro also plays the song within the tab, it has all the instruments, and you can slow it down. It's great.
Another thing to keep in mind is that you can find a lot of his backing tracks for free, or purchase them in a Hal Leonard play along book.
Also, this video does a great job explaining how to create your own songs in the style of Hendrix: https://www.youtube.com/watch?v=wR7SKgPNyZs
