Paul Daigle's class was great. He is in some ways advanced in teaching but he sits down with you until you've learned the songs. But, it's much easier class if you're actually in the intermediate to advanced ball park. For the first two years I went I took Dirk Powell, Ed Poullard, Wilson Savoy and Jason Frey. All were very informative and helpful. The past year I wanted to jump back a level because I wanted to learn some of Paul's style.
Charlie Terr, I have heard, is great for beginners if you feel you're in that ball park.
I'd also suggest finding someone with patience enough to show you some tricks and licks on the side. There will be some people who will be happy to help.
