Carbon fiber slides

An ultra lightweight carbon fiber slide can give you much more speed and accuracy in your fast playing. It also means way less stress and more focus on the music and less on your instrument. As a point of reference these slides weigh 85 grams. A PBone slide weighs in at 132 grams and a standard Conn 6h outer slide weighs a whopping 242 grams.

These slides feature all carbon fiber construction including the slide crook, brace and even the slide lock! They also feature an innovative Saturn water key embedded in the carbon fiber crook for a no maintenance, no cork solution.


Here is JT with the Dallas Horns playing a Butler trombones all carbon fiber outer slide.

Joakim Toftg̴rd РDallas horns

“I’ve been playing exclusively on carbon slides from Butler Trombones for over a year, and I won’t ever go back to a metal slide. The slide is so light that it requires minimal effort to switch directions, which really helps with my fast playing. It’s amazingly durable and won’t bend or dent. I’ve been using the slide both in the studio and for live performances, with no noticeable difference in my sound or in how the horn plays. I would absolutely recommend this slide to anyone who is looking to be more agile and effortless in their playing.”


Zach Steele – King 2b+

“It’s awesome! I was able to get my horn fitted with it the morning we left for tour.

5 shows in and it’s already settled sound-wise, I can hear everything and I’m getting point to my sound when I want it. Playing in the staff is like playing a tank now. Before I was actively holding back to not crack notes in the staff but the slide really lets me rip.

One of the other guys in the section could fit it straight onto his horn. His sound was immediately more full and resonant. It was pretty awesome to hear such a positive affect to his sound with it, the only negative I’ve heard of when using carbon fiber is a reduction in sound quality but that pretty much debunked the theory.

So far I’m loving it, enough so that I’m finally practicing daily because it’s fun to play!”


Dwight Stone – Kanstul 1606

“here’s the feedback on the slide…It is #$@% great…LOL… one advantage I didn’t even think of. When you are out in 5th,6th,7th position the weight of a metal slide puts strain on your left hand…plus… you tend to start using your right hand to help support the horn (a no-no). Through all positions it’s light and just floats… The repair guy really was impressed… then there was a pause and he asked…”Does it dent”… and I said no… he got a forlorn look and I patted him on the shoulder.”




Matt Hettwer – Bach 16

“I got the slide and I was amazed by it. It’s exactly what I wanted and I have zero regrets in buying it. I haven’t played my Bach in a while but from what I remember it sounds pretty much the same tone wise but with just a far superior slide. Maybe in terms of its sound it has lightened up a bit. Either way, I can play my old Bach again and that’s reason enough to be happy about it. The major thing that I appreciate though, is that the slide moves so efficiently now that my chops are not moving around and my buzz isn’t being interrupted as a result of unnecessary movement from a laggy slide. And that’s exactly what I was hoping it would do. My slide arm can move much more independently from the rest of body. Not to mention all of the outer positions are much more accessible which gives me a lot more choices as an improviser. Of course, playing on a traditional slide is not really a problem for me (I’m just high maintenance) but I guess because I like to constantly push my limits of what I can play, it’s really great to have a slide that will help me play freer. Thanks for the slide and for getting it to me so quickly! ”



Ray Mason, Taylor Swift, Laddy Antebellum – complete 6h custom slide

“I must say I am LOVING my brand new Butler Trombones carbon fiber slide for my Conn 6H bell. Still resonants well and is 1/8th the weight of my regular weight original slide…plus all the parts fit perfectly with my original slide from the 60s, so it’s like four slide in one each with slightly different characteristics!




Peter Dahlgren, lead trombone player in Norrbotten Big Band and Stockholm Jazz Orchestra – complete 6h custom slide

“I got the slide today and used it today at rehearsal. It works great, so easy to play on! So far I’m more than satisfied! It kind of transformed my old Conn into a very modern instrument.”





Dave Panichi – Buddy Rich – lead bone 82-85. Bob Mintzer, Blood Sweat & Tears, Slide Hampton’s World of Trombones.- King 3B

“I like knowing the slide is gonna be where it needs to be every time.
I think ballad playing is a little smoother & creamier due to the mechanical superiority of the slide.
The slide action helps fast line execution & clarity of sound.
Congrats on a great product ! Best of all I’ve started enjoying practicing again !”





Alex Jeun – Lawler – NY,NY

“Apart from getting an entire tongue transplant, fast passages seemed to be more fluid and natural. Perhaps that was the initial goal of the slide. However there’s another coincidental/incidental benefit: I was expecting some sound loss with the lightweight slide. But something about it has warmed up the low register, and the dreaded 5th, 6th and 7th position notes in the mid register seem to be more resonant, something I’ve been fighting with for a long time.

And you know what? All this time, I had not re-creamed or watered the slide yet (partially because I had just lost my last spray bottle). Imagine the best time you’ve Superslicked your slide (to me it’s the law of averages if I get it right, or horrible overdosed on gunk). Without even doing anything, the initial test felt like the best time I had done my slide…times 10!

Perhaps the price of admission is reading that it won’t dent or bend. I am a chronic slide end-meets-music stand smasher. And my current gig bag isn’t the safest, but very light and practical for subway travel. Having an impervious outer slide calms my mood.

People on the gigs thus far have said it sounds good, I was really testing its boundaries with volume and speed, and it was taking it like a champ.

Well done, David Butler. I say it’s worth it.”





We currently offer custom outer slides for several .500 and .508 bore instruments. The price for the custom outer slide is $800 US. The price for a complete custom 6h slide with carbon outer is $1,500 US. We are also taking pre-orders for bass trombone slides (.562/3) and large bore tenor slides (.547).

You also may buy as an option a 1606 Kanstul with a Butler trombones CF slide from Kanstul. Also Lawler trombones offers a .500 and a .508 Butler trombones CF slide as an option on their horns.

One note on lubrication. The carbon slide is best when it is dry and clean. I don’t use water at all as it slows it down from the surface tension between the outer and inner slides. I use a small amount of the Yamaha slide lubricant and run it all the way up and down the inner slides. I also frequently use a rod with a teary cloth sleeve to make sure the inside of the outer slide is clean and dry.


Please note: These slides are built perfectly parallel between tubes, however every horn is slightly different in the width between tubes and most likely will require an adjustment of width between your inner slides. This normally is not a very expensive adjustment that can be made by your instrument repairman. The ID of the outer tube is .540 for the .500 bore horn and .560 for the .508-09 bore horn. It is generally acceptable to have a gap of between .01 and .007 between your stocking and the ID of the outer tube. Before ordering it would be a good idea to measure with a digital caliper the OD of your stockings.
