Ivan, first off excellent work with all you lessons there some of the best of GMC. I love the blues and funk ones mostly this is why i'm requesting and In the Style of John Mayer lesson. He has got all the same influences as you and there is no one else here i believe that can do it as much justice as you.
John Mayer is one of the best composers alive today. His playing of his rhythm and lead riffs is flawless and is the best since probably Hendrix. I was hoping for a lesson that showed his mellow side to his fierce funk/blues licks and maybe a bit of his finger picking style. If not oh well.
Keep up the awesome work man.
