Managed to cut my own home-grown
slide last nite--and it sounds for crap! :? The strings on my reso don't sing against it, they buzz

.
I've gone through the thread, and I'm sure I constructed mine correctly, so my question is this--is there a difference in playing technique?
I've always used a heavy (like 4 ounces) chrome steel slide, and I love the sound. When I use the glass slide, things sound really back-porch falling down drunk to me--veerry swampy/buzzy, and not at all clean and clear.
Anyone?
