Introduction
When I was an undergraduate at the University of North Carolina in the early 1970’s, the Rolling Stones were in the midst of putting together an unparalleled run of four extraordinary record albums, including Beggar’s Banquet, Let It Bleed, Sticky Fingers and Exile on Mainstreet. This was not your everyday British Invasion band, but something new and powerfully different. Yes, it was the Rolling Stones, still largely blues influenced, but now exhibiting a richer, deeper, more expansive and more expressive music.
To my ear, there was something distinctly different about their guitar sounds too… at the time, I was unsure what it was exactly, but eventually realized it was the liberal use of bottleneck slide guitar. A sound so expressive to my sensibilities. Below you can see one of the Stones’ hard rockers from Exile on Mainstreet played live in 1972 in Texas. I saw the same show in Charlotte, NC that year. Note the characteristic rhythm riff driving the tune played by Keith Richards with the Mick Taylor’s bottleneck slide adding important textures over the top!
Besides adding sonic textures, the slide can be used to add important emotional context to a tune, which is even more appealing to me. Note, below for example, another video from the 1972 Texas concerts. This one of the Stones covering Robert Johnson’s classic Love in Vain from their album Let it Bleed. Mick Taylor’s slide work pulls at the heart. Suffice it to say I became enamored by the tones of bottleneck slide guitar listening to the Stones in my youth.
If you take the time to watch the above two videos closely, you will note that Mick Taylor plays two different kinds of slides to get two different tonalities, one metal in the All Down the Line, and a glass one in Love in Vain. Note too, that he plays with his slide like I do on his little finger, with the slide located above the middle knuckle of that finger. I will return to those observations later.
Where Did Slide Playing Come From?
This post is not a music history lesson, but I’ve read a lot about the blues. If my memory serves me well, the bottleneck slide playing that influenced early 20th century U.S. blues players originated among Hawaiian Islands Slack Key musicians and eventually migrated to the North American continent. Slack Keys are alternate tunings such as Open D and Open G, which are most common for bottleneck blues guitar play. What’s nice about open tunings is that the guitar is set up to play a rich chord with a strum across the open strings. In addition to popularizing Slack Key tunings, it’s also believed that Hawaiians introduced the use of a metal bar for sliding across the strings to smear (glissando) the notes and to create a wavering vibrato. It’s said that W.C. Handy, the man who first documented blues music was dozing at a railway station in the Delta region of Tutwiler, Mississippi. when he was awakened by an elderly African American man playing a haunting blues tune with smeared notes throughout. The old guitarist was using a pocket knife to create the glissandos. This apocryphal story might be the first recognition of bottleneck blues playing in the South.
My First Run with a Bottleneck Slide
I was taking finger-style country blues lessons some years ago in Cedar Falls, Iowa and had just purchased my first electric guitar, a fancy-pants Gretsch Falcon. About that same time, I ran into this bewhiskered old codger at the guitar shop where I studied. He was not capable of driving so his family would drop him off for lessons and later pick him up. I got to know him a bit, and at some point he told me he was learning to play bottleneck slide. I thought to myself, since I have this awesome electric guitar now, why not do the same and subsequently discussed it with my teacher. Shortly thereafter we went out on the shop floor and selected a glass slide off the rack and then I spent a few weeks futzing around with a slide on my guitar.
After a spell, I decided that slide playing was not a rabbit hole I wished to go down. I was just not adept enough at guitar playing yet, and the slide itself was an ill-fitting affair, being too large for me, thus difficult to control. Despite my initial lack of success at slide playing, I did conclude that I was most comfortable playing with a slide on my little finger, with the slide located above the middle knuckle. The middle knuckle location allowed me to properly position the slide on the fretboard without a lot of stress on my wrist, since I could simply bend my finger. Of course the Mo-Jo Slide would not work in the manner I wished as it swam all over my finger and the strings. I still have it and it makes a wonderful knick-knack on my music table.
Another Run with the Bottleneck Slide
Some months later with little to no intention of playing bottleneck slide again any time soon, I purchased a National Resonator (NRP Black Rust) from Reverb to play finger-style blues. This was based on my brief experience noodling around with a wooden Fender resonator in my local shop. The two guitars could not be any more different from each other. Whereas the Fender was set up to play finger-style with low action, the National had very high action, and I was distraught when I quickly ascertained that it would be next to impossible to play straight finger-style. It did not occur to me have have the guitar set up for finger-style.
Considering the substantial investment I made in the National, I decided then and there to return to bottleneck slide, since that was how it was set-up to be played. I was now committed to making a more serious run at mastering (take this term with a grain of salt) the slide.
Of course, the first order of business was to find a slide that would work for me and that ended up being an iterative process that still continues to this day. I needed to find a slide size and substance (i.e. material) that would meet my needs when playing my National. Since I like to play the slide on my little finger and above the middle knuckle, I needed a relatively small slide. So I went back to the store rack and searched for a smallish slide that would fit to my little finger above the knuckle. In this case I purchased a Dunlop Joe Perry ceramic slide, which was 50 mm in length. It’s worth a digression now to consider slide substances.
What Are the Most Common Slide Substances?
While there are lots of exceptions to the rule, slides are available in three common substances:
- Glass – lots of different types of glass tubes can be used for slides. Even though I was interested in playing a glass slide, I could not find one that would properly fit me… more about that later. Glass is the warmer sounding of slide materials with good sustain.
- Metal – lots of different metals are used, including but not limited to steel, nickel coated brass, titanium and solid brass. The metals give a harsher, biting sound, with somewhat diminished sustain and is favored by some hardcore country blues players.
- Ceramic – a non-metallic mineral that is said to fall somewhere in between metal and glass in its sonic properties. As indicated above, my Joe Perry slide is ceramic.
- Other – Taylor Guitars produces an ebony slide. It is a creative use of raw materials. I own one, but because of its somewhat muted sonic properties I hardly every use it. Their are other contraptions out there too that are claimed to take the place of original tubular slide designs. I have not tried any of them as of this writing.
Choosing a slide material is a very personal choice based on taste, your ear, and the type of tonality you are seeking. There is plenty of discussion about tonality of slide substances available on YouTube. There is no consensus on right or wrong choices. For example, despite my antipathy with the ebony slide, a quick survey of YouTube will yield a number of players who like it.
Getting a Slide to Fit Properly
I want a slide to fit my little finger snugly and I have yet to find one “off the rack” that does so. My method for customizing the fit is to pack the inside circumference of the slide with moleskin, a product typically used by hikers to prevent hotspots from turning into full blown blisters. The surface side of the the moleskin is a soft plush fabric and the back side is pressure sensitive adhesive. It requires patience and a good pair of forceps to get the moleskin properly positioned. If the slide is reasonabley close to fit, the moleskin will snug it up to my finger as you can see in the image on the left.
I’ve heard of other players who pack their slides with the fuzzy portion of velcro (too harsh) or with adhesive backed foam (durable?), but moleskin seems to me to be the best of the choices.
I Try A Variety of Slides and Resonators
Over the past few years my bottleneck playing has progressed nicely. My repertoire has grown in both Open D and Open G tunes. People love bottleneck playing. I’ve played frequently at Open Mic Nights to audience approval and have bought and sold several National resonators over the recent past. I currently play a National Reso-Lectric and an M1 Tricone. It is certainly possible to play bottleneck on electric and acoustic guitars as well; however, I myself prefer to play on a resonator. Nevertheless, I do play a nice Muddy Waters tune (Long Distance Call) on my Collings I-35 electric while in standard tuning and it is a lot of fun. Along the way I’ve worked with a variety of slides too:
- I was not that big a fan of the Joe Perry ceramic slide. It was too bulky and did not sound that good to my ear. Slide wall thickness and mass affects weight, tonality and comfort/accuracy while playing, so that element of slide design is an important consideration. As Ben Powell says, “mass equals tone.” Because of the wide variety of slide design choices, I found myself constantly shopping around. To that end, during my wanderings around the internet, I discovered Ben Powell’s fascinating Tone Dome slide. Below you can see Ben discussing his innovative slide design:
As Ben illuminates, the Tone Dome is designed for the little finger and to fit above the middle knuckle. There’s a cut out to enable easy finger bending too. At the time I purchased one, what was available was a nickel-plated brass version and I played it for a long, long time. The Tone Dome was relatively light and easy to manipulate on the fretboard. The tonality was a typical metallic bite with reasonable sustain. My only quibble was the slide did not cover the full width of my fretboard, which was problematic for full chord slides. Ben is such as accomplished slide player, he does not seem bothered by the shortness of the slide, but I was. To reduce this problem but not eliminate it completely I positioned the slide reversed from the way Powell intended it to be. In addition, I added a bit of moleskin within the slide to adjust the fit.
- Even playing the Tone Dome reversed on my guitar, I became frustrated with it’s lack of fretboard width coverage for certain full chord tunes like Spoonful and went back out into the marketplace. To that end, I found a web-based seller of elegantly designed ceramic slides out of the UK (Star Singer) that looked more useable than the Dunlop Joe Perry version I had tried earlier. I purchased a 57 mm length version as can be seen on the right. I liked the Star Singer just fine and for tunes that required full fretboard width coverage I used it. Nevertheless, my workhouse slide remained the nickel-plated brass Tone Dome because I preferred its tonality more than every other slide I’d used to date. Finally, the Star Singer is a bit fragile and I tend to be a bit clumsy sometimes and after a drop or two, it has a micro crack on one side, so I have to be intentional when positioning it on my finger. For that reason, I rarely use the Star Singer anymore and just tough out the full width chords with the Tone Dome by faking it!
- While noodling around the National Reso-phonic website, I stumbled across the fact that they now sell Ben Powell Tone Domes. Besides a stainless steel version, they also offer a beefy solid brass one too, which I immediately acquired. The increased mass of the new solid brass slide gave it a more present, warmer and rounder tonality such that it completely displaced my original Tone Dome, which is now retired.
To the left you can see both of the Ben Powell Tone Domes that are offered by National Reso-Phonic on their website. I really like the solid brass version and have used it with success for several years now. As with my other slides, I’ve inserted some moleskin to tighten the fit around my little finger. I’ve used this slide on all my resonators, and my Collings electric guitar with nice effect and tonality. My only quibble is that on cold, low humidity winter days, the brass slide creates a static crackle when I play it on my National Reso-Lectric!
- I was pretty enamored by my solid brass Tone Dome for a long time and used it at Open Mic Nights and during my lessons at the guitar shop. Sometimes during lessons, my teacher would demonstrate a point he was making about phrasing or slide technique on his own electric guitar and he would use a simple clear glass slide on his ring finger. His enviable tone always amazed me. The notes rang like a bell and sustained far longer than I was achieving with my resonator and brass slide combination. When I commented on his tone, he would strongly suggest I revisit using a glass slide. If it was good enough for Duane Allman, it should be good enough for me. My usual response was that I could never find a glass slide that would fit my little finger properly and then we’d drop the subject.
Then one day, scrolling through my Facebook feed, I noticed Blues/Americana aficionado and online teacher Tom Feldmann extolling the virtues of Diamond Bottleneck’s glass slides. Sometime thereafter I explored their website and discovered that a host of luminaries like Mike Dowling and Mark Knopfler also used Diamond Bottlenecks. Good enough for them… good enough for me, so I decided that I would purchase one! I then began a back and forth correspondence with head/lead consultant Ian McWee of Diamond Bottlenecks, which took place over several days. Ian was a combination of cordial, patient and very responsive.
If you peruse the Diamond Bottleneck’s website, you will see that they offer glass slides in a wide variety. From sawn of necks of actual former bottles, to hand blown soda ash or leaded crystal and more. Using old school, British, precision, hand skilled craftsmenship rooted in the birthplace of the Industrial Revolution, Ian and his team manufacture their slides onsite in a small factory. Below you can see a brief video of Ian fashioning a glass slide.
I decided to order a slide from their Ultimate collection, which is comprised of leaded crystal. The lead crystal process produces a high density glass with unusual visual clarity. Theoretically, the higher density glass should enhance tone and and sonic sustain. Ian sent me images of the leaded crystal glass that he had in his inventory, which can affect what you can order at any given time. As I understand it, the slides are cut from long glass tubes and then finished to customer specification. In the end, I determined that ordering three slides would be the most economical route, since there would then be no shipping fee with an order that size. All three slides were to come in around 50 mm length, with inner diameters close to the size of my little finger. Two were open ended with copper and ruby red colors and wall thicknesses of 6 & 8mm, and the other was a double-walled affair with a dome. We thought this variety would allow me to find a slide “sweet-spot.”
It took a while for the package to arrive from the UK, mostly because the USPS quarantined the shipment in Chicago for over a week! I was told it was some kind of new safety protocol causing the delay. The slides were well packaged arriving in their own individual velveteen bags in pristine condition. Both my wife and I were delighted with how beautiful the glass was!
I post below a sound sampler of the three new glass slides from Diamond Bottlenecks and for reference, I’ve also included a sample of my National (Ben Powell) Solid Brass Tone Dome. You’ll note that I am playing a 2021 National Reso-phonic M1 Tricone. The tune is the first verse of Blind Willie McTell’s Wake Up Mama. The samples are ordered as follows:
- Diamond Bottleneck Ultimate – 50mm (Plus) Double walled with dome; Dark Blue Colored
- Diamond Bottleneck Ultimate – 50mm Open Ended 8mm thick Wall; Ruby Red Colored
- Diamond Bottleneck Ultimate – 50mm Open Ended 6mm thick Wall; Copper Colored
- National Reso-phonic/Ben Powell Solid Brass Tone Dome
Truth is I like all four of the slides sampled; however, I am really fascinated by the glass slide tones. Both my wife and I noticed right away the bell-like chimes and longer sustain of the new Diamond Bottlenecks. I think the most “present” tone comes from the large domed slide, which is not surprising as it is the most massive of the bunch, which is also a problem as the slide is really heavy and causes me some reluctance to play it. I did apply some moleskin to the interior of the glass dome so it stays well put on my finger… but it’s weight could be a deterrent to my using it very often!
I am very happy with both of the open-ended glass slides, though if pressed I would probably choose the thicker walled ruby red slide because its tone is just a bit thicker than the copper colored slide. Both open-ended slides are easily playable though they do not fit snugly to my little finger. As a result, I am concerned with dropping and breaking the slides, but am also reluctant to apply moleskin to the interior of these translucent slides adversely affecting their appearance… still weighing this decision as I write.
Thanks for tuning in… leave a comment if you wish…
Post Script:
I added a thin band of moleskin to the lower opening of the Ruby Red slide and it now locks onto my finger much more effectively. Hopefully this will minimize the potential for dropping off my finger! This small band of moleskin has not adversely affected the beauty of the slide, nor has it affected it’s lovely tone.
