Tuba Mouthpiece CONN Helberk 7B

I am selling this because I purchased it in the past and am now using a different mouthpiece.

■Specifications (Reference)
・Rim inner diameter: Approximately 32.0 mm
・Bore diameter (throat): Approximately 8.3 mm
・Cup: Medium V-cup (Medium Deep, funnel shape)
・Shank: American shank

This model is a standard CONN tuba mouthpiece based on the traditional Helleberg shape.

The characteristic funnel shape of the Helleberg provides stable sound initiation and a focused, cohesive sound.

* Funnel shape refers to a structure where the inside of the cup gradually narrows like a funnel, designed to achieve a cohesive sound and stable low notes.

The 7B offers a slightly more open blowing feel than typical Helleberg models,
making it easier to produce a rich, grand sound with good breath support.

Recommended for those seeking deeper low notes and a more symphonic resonance than school-standard mouthpieces like the Bach 24AW or YAMAHA 67C4.
If you're looking to enhance the depth and presence of your sound for competitions or concerts, please consider this mouthpiece.

A great feature is its compatibility with many major instrument manufacturers, including Yamaha, Bach, B&S, and Meinl Weston.

There are minor scratches from use, but they do not affect playability.
We encourage those who want to try out the fit and blowing feel to consider this opportunity.

■Condition
There are minor scuffs on the shank and other areas due to use,
but there are no major scratches or dents, and it does not affect playability.

Please feel free to comment if you have any questions.
