Randefalk X-Range Tuba SHANK ONLY

The Randefalk X-Range is a two-piece tuba mouthpiece system, allowing you to choose your preferred cup and shank separately. This means you can keep the rim and cup you like while changing the shank to alter the feel, response and suitability for different instruments.

A replacement shank, or a spare for switching instruments or ranges on certain repertoire.

I choose to play Randefalk mouthpieces for the combination of flexibility, clear articulation, secure intonation and consistent tone quality throughout the register. For me, production feels particularly effortless because of the cup shape.

My main setup is the R3SX with an 8.2 shank. For solo playing requiring particularly demanding range, flexibility or technique, I use the smaller R4SX with an 8.0 shank.

Shank Options

8.0 Shank

• 8.0mm throat
• 11.40mm backbore
• Particularly suitable for Eb and F tuba
• Recommended with the smaller R4/R3 cups

8.2 Shank

• 8.2mm throat
• 11.40mm backbore
• Suitable for Eb, F and CC tuba
• A very versatile middle option
• This is the shank I use with my R3SX

8.2L Shank

• 8.2mm throat
• 11.80mm backbore
• Particularly suitable for Bb and CC tuba
• Larger backbore for the bigger instruments and cup sizes
• Recommended particularly with R1/R1.5 cups

All three shanks are interchangeable within the X-Range, so you can experiment with different combinations while keeping your preferred cup.
