MTS Products1203V Large Frame Top Action Tuba Case Black
1/4
Independent shopping perspective
The Korena take
A black case for large-frame, top-action tubas. For players with a big piston horn who need transport protection sized to it.
Strong match
Who this is for
- Top-action piston tuba players moving the horn regularly
- Large-frame BBb or CC horns that don't fit standard cases
- Programs replacing cases on full-size concert tubas
Consider the trade-offs
When to look elsewhere
- Front-action or rotary tubas with different valve placement
- Smaller-frame tubas that would shift inside
- Players who never move the instrument off a stand
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
Large frame
Built around a full-size tuba body. A smaller horn will have room to move, which is its own risk.
Detail 03
1203V model designation
MTS sizes cases per horn frame. The model number, not the word tuba, tells you what actually fits.
Detail 04
$849.99 price
Priced against the horn it protects. Full-size tuba cases cost more simply because of their volume.
Detail 05
Black finish
Neutral in ensemble settings and forgiving of the scuffs a case this size will collect.
Final check
Know before you order
- 01Case only. No instrument included

- 03Measure bell diameter and overall height against the case interior
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What does top action mean?
The pistons sit on top of the valve block rather than facing forward. The case interior is shaped around that layout, so valve orientation matters for fit.
02Will my rotary tuba fit?
No. This is cut for a top-action piston horn, and a rotary tuba's valve section and wrap sit differently.
03How is this different from the 1207V?
Different frame fit. The 1203V is specified for large-frame top-action horns; match the model number to your tuba rather than choosing on price.
04What color is it?
Black.
