Valve Trombones R us

Welcome to the Only Online Valve Trombone (& trumpets) Store in the World!

 Welcome to the Only Valve Trombone Store in the World

Featuring the legendary Conn Valve Trombone, restored and customized with first and third valve slide trigger assemblies and our special engraved counter-weights that we call the “Triple C”

We have other makes of valve trombones available.  I’ve test played them all both before and after Corky’s restorations/customization, then I rinse them out and list them for sale. They all are good playing horns, all of them improved from their original designs or they wouldn’t be on this site.  We also have a limited number of Conn and other makes of slide trombones available, including two beautiful Reynolds bass trombones. All the horns are special and we try to make each one unique in some way. 

I’ve known about Olds trombones since 8th grade. They have always been highly regarded.  The P-16 Custom was the last “top of the line” small bore Tenor trombone that Olds manufactured before going out of business around 1979. We have just added to Olds P-16 Custom slide trombones, an Olds R15 Recording trombone and a Reynolds TO-02 bass trombone.

If you want your name added to our list of valve bone players, send me an e-mail at vtbone1@aol.com   

You will also find a list of all the recordings in my private library that have a valve bone somewhere

We continue to thank Christine Derksen of The Conn Loyalist website for her permission to use her article as part of presentation in the informational section about Coprion bells. 

Please, look around to see if there’s anything you like.  

I want this website to be a resource. Feel free to contact me with questions or comments or something you think I might be able to help you with or something to help me and others seeking information about valve trombones.  

Because we’ve sold bass trombones with Thayer axial-flow valves (a Conn 71H with a single Thayer, a Reynolds 78-X and a Holton TR-180 with double Thayer) and have a 2002 Conn Limited Edition large bore tenor slide trombone with a single Thayer for sale on the website, I decided to post some axial-flow valve maintenance tips from Barb Thayer. Thanks Barb!

You can reach me directly at vtbone1@aol.com

2014 was a rough year for us.  First, our photographer, Jeff Peronto finally succumbed to cancer in February after a 13-year battle. You'll find some information about Jeff ion his bio page.

 Second: On November 18th, “Corky” Cain, the genius behind the restored and customized instruments on valvetrombonerus.com passed away at the age 84 from massive infections after surgery to remove the lower lobe of his right lung along with a malignant tumor. Corky’s last project for valvetrombonesrus.com was the installation of a double-Thayer valve unit on that Reynolds 72-X bass trombone for a customer in Arizona. 

You’ll find a not-so-brief brief biography and some pictures of Corky in his bio section. 

We continue to thank Diego Urcola for providing the pictures of his “Triple C” with some pretty exclusive company! (One of Corky’s last two projects for this website was to do some work on Diego’s Conn valve section….the circle closing.) 

Remember, the sound is the thing and that’s why we love Conns!

PS:  I like those History Channel shows like Pawn Stars, Counting Cars, American Restorations and American Pickers. We’ve been around longer but they are a little bit of what we do, especially Counting Cars and American Restorations.  Our goal is to save these instruments, make them look like brand new and play better than new.

I was practicing on the Conn (71H bass bone, nickel-plate over yellow brass bell, converted to a single Ed Thayer axial-flow valve--BR) early this morning. I am very happy that I decided to purchase this instrument. I like the way it plays and really like the clean lines of the instrument. The workmanship is immaculate. Please give my compliments to Corky. He is an artist in my opinion. Everything works well; the slide, the valve, even the tuning slides work better than any I've ever had.
