I love playing slide,not to good at it though.
I bought a Gretch historic series resonator,not quite a Dobro,but sounds good for the price.
Martin sells Dobro strings,16 gauge if you can believe it!
I put them on,sound good but all you can play on them is slide,unlessyou have iron fingers!
The only way I found to minimise noise is to lay all your fingers on the strings behind the slide,and mute a little with your thumb on the pick hand.
Robert Johnson,now there was a slide player.
I guess you have to sell your soul to the devil to play that good though!
