Dylan Harp
Here's a site devoted to Dylan's harp playing. I don't want to be negative, but I am not sure if this is a good thing. I get more questions about Dylan than any other harp player. Number 2 is Lennon, and number 3 is Popper. This is a sad comment on the state of the world.
However, this page answers all the questions about what kind of harp Dylan played and even has some tab.
I like Dylan quite a bit, but I try not to listen to the harp solos. 

 

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.
