Detail 01
4/4 size
The full concert size. Big bore, big sound, and it takes real air support to fill the horn.

Independent shopping perspective
A 4-valve 4/4 BBb tuba at the professional tier. For a player who already knows what they want out of a full-size horn.

Strong match

What matters in use
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 01
The full concert size. Big bore, big sound, and it takes real air support to fill the horn.
Detail 02
The default American band key. Standard fingerings, and every band part is written with it in mind.
Detail 03
Fourth valve closes the range gap under low E and pulls low D and C into tune without lip correction.
Detail 04
Career-instrument pricing. The money buys tolerances and even response across registers, not extra hardware.
Detail 05
A distinct model line from the 186 — different body, so play both back to back before choosing.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Both are 4-valve 4/4 BBb tubas. The 187 sits higher in price here. They are separate model lines, so the honest answer is to play both and pick by feel.
For band and most orchestral work, yes. Four valves cover the low range and fix the worst intonation problems. A fifth valve is for players doing heavy low-register solo repertoire.
No. This is the opposite problem — it is more horn than a beginner needs. It is a buy-once instrument for a committed player.
A standard BBb tuba mouthpiece. Size is personal — larger cups give more low-end volume, smaller ones make the upper register easier.
