Overview
A school band room is where this Yamaha tuba is meant to live, with a three-quarter size body that suits younger or smaller beginners. It has three nickel-plated top action valves, hand-lapped pistons and slides, and a bell flare designed for projection. A case and a mouthpiece come with it.
The reason to buy is a complete starter package: a smaller tuba with a case, a mouthpiece and hand-lapped valve fit. The limit is that the listing carries a weight figure that cannot be correct, and the shipping dimensions are large.
Who it's for
Beginners in a school program, and parents renting or buying a first tuba, will use the smaller body and the included case. Players who need a full-size instrument or a rotary valve system should look elsewhere.
Pros and cons
- Smaller size for beginners
- Case and mouthpiece included
- Hand-lapped pistons and slides
- Nickel-plated top action valves
- Weight listed incorrectly
- Large shipping dimensions
- Warranty not listed
- Three valves only
Performance notes
Hand-lapping of the pistons and slides is described as giving quiet, responsive valve action. The bore and bell flare shape the tone, which the listing describes as warm and rich. An extended taper on the leadpipe is credited with centering notes.
