It's sometimes about "how" we practice as opposed to "how much." You learning as much as you have from the site in a short time is a true testament to that. Glad we could help!

If you are into funk guitar styles, I have done a few tutorials on some R&B funk tunes that I think would really help you get some of those concepts under your fingers. Check these out.

Chaka Khan - Sweet Thing
Parliament - I Wanna Testify
Isly Bros. - It's Your Thing

I also did a John Mayer Artist Study a few years ago as well. It's solely on his acoustic playing, so if you are into that here it is.

Enjoy!
