I have a Dunlop brass slide. Don't like the fit, don't like the sound. Not sure why. I seem to get a deadened sound instead of the tone I expected from brass.
Thanks to Shane Speal's StubbySlide.com (not an affiliate link) and New Orleans artist Ron Hall for coming up with The Preacher.
From now on I'll spend the extra couple of bucks to buy a quality slide from Shane (and the slide guitar lovers who make them for him) instead of grabbing whatever I see cheap at Amazon or Guitar Center.
