Dunlop 266 Mudslide Porcelain Slide, Large

Not as slick as Pyrex, brass pr chrome, this slide still has a nice, resonant tone. It seems to me to being closer to glass than other ceramic slides I've used, but is, again, not quite as slick. It also has a substantial feel, and is a bit thicker than Dunlop heavy Pyrex slides, and a lot thicker than heavy brass slides. I don't have particularly large hands (what Dunlop calls a medium usually fits my pinky about right), and this slide fits perfectly on my pinky. I've had good results on both resophonic and electric guitars.

Good. Heavy. Has a slightly gritty feel on the strings. Some people complain that it won't go past the last finger joint, but you really shouldn't want it to for playing regular slide guitar.

Love it. I don't have big hands, but the large sized model is only slightly too big and only needed a couple of band aids inside of it to get a perfect fit - something I do to all my slides.

Arrived quickly. Was hoping it would fit over my ring finger but won’t get past my first knuckle. It does fit on the small side but beautiful quality from Dunlop as usual.

So I have three slides -- glass, chrome, and the new porcelain mudslide. Pros of the Mudslide are how it fits my finger and deep rich tone. Cons are that it is a bit heavier to maneuver than the chrome or glass so it does affect speed a bit up and down the neck. And, it is less forgiving due to its large diameter. In other words, you have to be dead nuts on the fret otherwise it sours the note a bit which kind of goes against the principles of slide which is moving the finger back and forth a bit for some vibrato and sustain. So with that said, the thin wall chrome is still my go to slide. But when I want to slow down and experiment a bit with deeper, richer tones, I reach for the mud slide. As for the glass, it does not ring enough for me like the chrome slide.
