The Bob Reeves/Brass Ark Mouthpieces for Trombone

We are pleased to announce a collaboration between Bob Reeves Brass Mouthpieces and The Brass Ark, creating an exciting line of premium trombone mouthpieces. Initially we will offer five models with more in the pipeline. Introducing, on specific request, a revolutionary shank system allowing customization for the professional to fine tune the penetration of the mouthpiece into their instrument's receiver. Various shanks and rim combinations are also available as special options.

Bob Reeves Brass Mouthpieces is a world renowned maker of the highest quality hand crafted mouthpieces for professional trumpet players for over 50 years. The Brass Ark, established in 2010 by trombonist Noah Gladstone, celebrates the love and passion for legendary brass craftsmanship and brings it to the forefront of musicians' minds through the development and cultivation of modern equipment that firmly establishes its roots in the classic designs of the vintage masters.

We are very excited and proud to see this mouthpiece project come to fruition. Bringing a premium line of hand crafted mouthpieces, available to the trombone community, has been a dream for both companies. The Bob Reeves/Brass Ark mouthpieces are some of the finest ever produced and we are confident that our philosophy of bringing rare and classic designs integrated with the modern mainstream has created something very special.

With regard to the design concepts: we were striving to find a mouthpiece that responded with vibrant clarity, a nice interface for the performer to get the maximum efficiency and production with the minimal amount of effort. The articulations speak with brilliance and definition, while the "bloom" of the tone is rich and full with a focused core that not only projects but enhances the quality and characteristic of your instrument.

Now available for immediate shipping! Sizes not in stock or custom orders will ship within one week of your order. Our sizes available: 11C, Clarke 6.5AL, Clarke 6.5AL Large Shank, 5GS, 5G, 4G, 5G-4G, 4G-5G, the "Mr. Bass Trombone" 1 1/2G and The "Orchestral" Bass Trombone and The "CV" Bass Trombone.

    "Reeves-Brass Ark "Mercury" Trombone Line

    Inspired by a rare trombone mouthpiece made by a famous mouthpiece maker in the early 1920s (before he started a famous Brass Corporation in New York, Mt Vernon and Elkhart). We knew we could come up with an updated trombone mouthpiece that captures the essence of a bygone era. The new Bob Reeves-Brass Ark "Mercury" trombone line offers our standard pieces with the option of another outer shape. This new design yields a vibrant, timeless sound with predictability in color, response and familiarity.

    The Mercury blank is available on any mouthpiece that we offer, and only available on the small shank 11C and Clarke mouthpieces. Each size mouthpiece has a specific blank that is designed for that size, to help maintain proper visual proportions but also retain a balanced weight and sound. No extra charge for a Mercury blank.

    Sleeve System
    Bob Reeves developed his sleeve system on his trumpet mouthpiece to help players fine tune the gap between the end of their mouthpiece and the start of the leadpipe. We thought it interesting to develop a similar system to allow trombonists to adjust the penetration of their shank into their leadpipe. Not only does it allow you tailor your piece to your instrument, but it also allows you to change the shank taper (i.e. Morse, Remington, Euro etc) without changing to an entirely different mouthpiece or ordering a new backbore.

    The Reeves/Ark sleeve system is available for no additional charge when ordering one of our mouthpieces. Each sleeve is $35 each in silver. An existing mouthpiece can be adapted for sleeves for $50 in silver and if you're interested in that please send me an E-mail for instructions on delivery times.

    These online ordering systems are designed to allow clients to purchase basic models. If you're after a custom size, lexan rim, ordering additional rims or cups or anything else that isn't listed here it is best to Send an E-mail. If you'd like something custom or just want some advice on which mouthpiece direction would be best for you, please ask me. I'm happy to help offer a personal consultation. If you order a mouthpiece cut for sleeves, I will invoice you for the balance of your sleeve cost.
    Please note that orders from Japan should go through our exclusive dealer, Joy Brass. Custom orders can still be ordered from me directly.
