These modification were done to Doug Yeo’s Yamaha bass trombone. I have included a link to his blog post/review.

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.”

Michael Nelson 16M conversion. 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!!!)
