Over the years, i've bought and used numerous slides. I prefer slides which are more secure/fitted (no Coricidan bottles). I love the knuckle slides and the Dunlop Shy Slide for still allowing the use of the fingers for fretting. I love glass for its smoothness, my Mudslide and Bigheart ceramics for their weight and smoothness, and my brass slides for being durable. A few months ago, I was considering getting a Peaceland Guitar Ring to have something a little wider than a knuckle slide, but which still allowed full finger use. As I'm searching for user experiences, vids, and so on, I stumble across the Jetslide. http://www.jetslide.com It's a ring with a slide bar attached, but goes beyond the rotating slides of that sort by coming into play when you grab that tab with your pinky. It looks cool in that it supposedly gets out of the way when your pinky isn't on the tab. The various videos I find show people using it just as described with no problem. So, I decide to order one, the brass (for weight) with the glass sleeve (for smoothness). The website has instructions for determining the correct size, but they offer a free exchange in case your sizing fu isn't up to snuff. I did the described paper tape procedure on their website, and then went to a jewelry store to double check, and the two measurements were identical. I placed the order. It arrived. It takes no time at all to incorporate it into playing. Switching back and forth between use and release is fast. One of the stranger aspects to me is that when I'm using it, it feels weighty, like a heavy steel guitar tonebar. Even with that feeling of weight though, it feels completely secure just using the ring finger and pinky. It's semi-adjustable, but since it currently fits perfectly I can't comment on that aspect of using it in the long term. I also don't leave slides on top of equipment (which is why my ceramic slides are still going and not broken), and when I use the Jetslide I anticipate leaving it on or having it in my pocket. The ease of use makes me think that slide will be an easy flavor/texture to add even for just occasional vibrato, as opposed to "Here's that song where I pull out the slide." I even threw out a maqam scale, different from the western scale, because it was easy to just toss it in. I also use eBow a lot, and I'm looking forward to combining this with woodwind sounds and even bass flute sounds like the shakuhachi, but with flexible pitch. I even used it with a synth pedal to play that glissando riff from the Doctor Who theme. I've never seen another slide which was so fast to bring in and out of play. I am *extremely* happy with my purchase.
