Great thread topic. I've been hanging around here a few years but hadn't seen this one. Good on 'ya whoever gave it a bump!
I learned a very long time ago I would not be EVH, so I focused a lot on slide playing. My biggest inspiration is Duane, and to my (crappy slide playing) friends, I am leagues above them. Ha, ha...
But I am no where near where I want to be. Duane's playing was so vocal. As much as Hendrix then Eddie turned playing on it's head, and changed the traditional arc of development, I feel Duane did the same for slide. Clapton's slide playing, Page, even guys like Taj Mahal. They all took the Robert Johnson, Elmore James stuff and moved it forward. Duane pushed it years ahead with 1 album. I have not been as diligent as I used to be, but I love playing. I was in an acoustic duo for a long time. I would bringing my resonator to gigs to change songs. I would figure out horns, or piano, and other instruments to fill the song with the melody using slide. The reso has a huge neck, so I could comfortably tune to open E (my personal favorite) but I'd use G a lot too. When I play electric, it is almost always E (Duane). I have an old Vantage double cut-away set neck. If I need an E, and a G, I bring a Tele for the G tuning.
As for my slides. I've tried almost all of them. I am a pinky player, so I prefer a smaller one. I use high polished chrome if I want metal, or a homemade one from a wine bottle if I want glass. I sometimes buy a wine at the LCBO specifically if I think it would make a good slide. (getting harder with all the screw caps makers are going with). I have a tapered acrylic one a friend brought back from NYC that I rarely use outside of the house, cause I ain't getting to New York anytime soon to replace it.
Again, great thread. I will drop in on this one often!
