Glass Slide

I bought one a long time ago and for years it just looked at me from the top of my amp. Finally, I re-tuned one of my guitars to open A and learned to play In My Time of Dying.

Go to resale and antique shops and find an old Coricidin bottle. You have to hunt quite a bit but they are out there. So far I've found two and they are the best slides. The repros by Dunlop feel different and are too "slick", as are Pyrex slides. Others I use are a Dunlop Mudslide (ceramic), a tapered machined brass one (don't recall brand), and a slim Pyrex that fits on the pinkie. Normally I use the slide on my ring finger. But those old bottles are still the best.

You still should learn chord shapes for open tunings as just sliding up and down making bugle calls gets monotonous. Also learn to damp strings and play single notes.
