Detail 01
Fiberglass body
Much lighter on the shoulder than brass and far more forgiving of field knocks and temperature swings.

YamahaYSH-301 Series Fiberglass BBb Sousaphone Ysh301 Sousaphone Only
Independent shopping perspective
The Korena take
Full-size BBb fiberglass sousaphone with three piston valves and a front-facing bell. Built for marching programs that need a durable, carryable horn.
Strong match
Who this is for
- Marching band and drum corps carrying the horn on the field
- Schools needing a low-brass instrument that survives daily student handling
- BBb tuba players moving outdoors without relearning fingerings
Consider the trade-offs
When to look elsewhere
- Concert or orchestral tuba work, where an upright horn fits better
- Middle-school players too small for a 4/4 body
- Anyone wanting brass tone and the weight that comes with it
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
ABS resin bell, 26-1/8 inch
Keeps weight off the far end so the horn balances better, and it won't dent like brass.
Detail 03
Front-facing bell
Projects sound downfield toward the audience instead of overhead. Standard marching orientation.
Detail 04
.728 inch bore
Medium-large. Moderate air resistance, so young players can fill it without overblowing.
Detail 05
Three piston valves
Standard marching setup. The low register below the staff needs alternate fingerings and lip correction.
Detail 06
BBb key, 4/4 size
Same fingerings as a standard BBb tuba, so players switch between the two directly. Sized for adults and high schoolers.
Final check
Know before you order
- 01No case or gig bag. Transport and storage protection is a separate purchase.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does it come with a mouthpiece?
Yes, a Yamaha 67C4 is included. It's a general-purpose size that works for most school and marching players.
02How much lighter is fiberglass than brass?
Enough to matter over a full rehearsal. The fiberglass body and resin bell are the main reason marching programs choose this over a brass sousaphone.
03Can a tuba player pick this up right away?
Yes. It's BBb with three pistons, so the fingerings match a standard BBb tuba. The adjustment is posture and bell direction, not notes.
04Is a case included?
No. You'll need a separate case or fiberglass sousaphone shipping case for transport and storage.
