I have an acoustic and a semi acoustic at the moment, though I am thinking of looking into a resonator (GAS creeping in!!).
As I am fairly new to all this I am happy to explore different tunings and see which grabs me - try anything once as my ol' gran used to tell me ('cept for incest and Morris Dancing she would add!).
Came across Bob Brozman the other day and was suitably impressed - something to aim for! Love the Ry Cooder stuff. And, of course, mustn't forget Mississippi Fred McDowell.
Is there much duplication on Griff's two slide courses?
I'll have a look at David Hamburger - I haven't heard of him before but sounds good, thanks.
