Custom carbon fiber modifications

Custom carbon fiber modifications for your horn

We can modify any horn with a new interchangeable carbon fiber bell. Our available bell sizes are 8", 8.5" and 9.5". The most popular mods are for bass trombone as it "changes the game" with a dramatic loss of weight. We can now add CF mods to one of the most popular horns, the Bach 42. We can make your bell interchangeable with our CF bell and also build a complete slide section with our curved brace and interchangeable lead pipes. Email us your idea for quote and availability. The all up weight of the 42 with our mods is 3 lbs. More importantly it moves the weight just on your shoulder and reduces all the weight on the ends.
  • Carbon fiber bell (8", 8.5" and 9.5")
  • Carbon fiber bell flare only for cut bells (you supply the threaded bell ring 8", 8.5" and 9.5" )
  • Carbon fiber two piece cut bell with aluminum or standard brass threaded rings.
  • Detachable CF bell with interchangeable original brass bell (standard fittings are Edwards style)
  • CF outer slide for all make and models. (see slide page)
  • CF bell flares for 8", 8.5" and 9.5" bells. You supply the bell ring part and we build your CF flare to fit your brass bell stem.)

King 3B carbon fiber bell and outer slide conversions

We can convert a King 3 or 2B bell to carbon fiber and build outer carbon fiber slides for these horns as well. These horns play great!

 

Here is another 3B conversion with a 2 part epoxy matte finish on all metal parts. This should last a lifetime!

Super Bone conversion

Rafi Malkiel

This was a fun project! We built a carbon fiber bell as well as the short carbon fiber outer slide. We also cut the bell for ease of travel. It made the horn so much more playable!

Yamaha bass trombone conversion

Doug Yeo, former bass trombonist with the Boston Symphony Orchestra

"To say that I am enthusiastic about what Dave Butler has done would be a profound understatement. My new carbon fiber parts as installed on my YAMAHA YBL-822G bass trombone have given me an instrument that is highly responsive and lightweight but has a sound I would expect to be produced by my fully brass and nickel bass trombone. Dave Butler’s work with carbon fiber will allow me to continue playing the trombone for many more years as a result of the instrument’s reduced weight and great responsiveness. We are witnessing one of the most significant developments in trombone design and manufacturing since the invention of the F-attachment in 1839. This is not an exaggeration; of this I am quite serious. The future is now."

Bach 16M conversion

Michael Nelson - Horn Heads (Prince's former horn section).

I'm really diggin' my 16M w/Butler carbon fiber slide and bell flair. This show was it's first trial run right after I got it. I think it's going to be my go to funk horn.

Hear Michael play this horn: (btw aside from hearing Michael play this horn, this is a GREAT show!!!)

Crazy 007 conversion, shaken not stirred!

Kevin Jones, FSU jazz trombone professor.

Kevin wanted an ultra compact horn that he could put in his backpack. He uses a pool cue case for the slide section! We cut the bell and then cut the bell again using a slip together joint betwen the gooseneck braces. It came out suprizingly fine and plays great!

Greenhoe bass trombone conversion

John Fitzmaurice

We took pounds off this bass trombone! We built a CF bell and outer slide to keep the weight only over the shoulder and very little on the ends!

Edwards T-454 bass trombone conversion

Roland Huie Jr

This was another really heavy bass trombone that we converted to a horn that can be played for hours with little stress on the arm, shoulder and wrist.
