Sooner or later a band director suggests that a young trumpet player is ready for a better horn. Before you shop, it helps to know what actually changes as you climb from a student trumpet to a step-up model and then to a professional one. The answer is less than the labels suggest.
The bore barely moves
The bore is the inside diameter of the tubing, and on the trumpets most families buy, it hardly changes. Yamaha's student YTR-2330, its step-up YTR-4335GII and its professional Xeno YTR-8335II all have the same 0.459 inch medium-large bore. Bach's student TR300H2 is 0.459 inch, the upgraded student TR400 is 0.460 inch, and the professional Stradivarius 180S37 is 0.459 inch. A player moving up isn't moving to a bigger bore. The changes are in the bell, the mouthpipe, the weight and the build.
Student trumpets
The YTR-2330 has a two-piece yellow brass bell, 4-7/8 inches across, Monel pistons, a medium-weight body and an adjustable third slide trigger that fits a small hand. It comes with a Yamaha 11B4 mouthpiece. The Bach TR300H2 has a two-piece yellow brass bell of 4-3/4 inches, a rose brass mouthpipe and a thumb hook on the first slide.
Bach's TR400 sits a rung higher, though Conn-Selmer still files it as a student trumpet. Its parts listing gives a red brass mouthpipe, Monel pistons, a first slide thumb hook, deluxe engraving and a backpack-style case. Think of it as Bach's upgraded student horn.
Step-up trumpets
Yamaha's step-up model is the YTR-4335, now in its GII version, which Yamaha Japan released in November 2012. Next to the YTR-2330 it changes two things. The bell is gold brass, which Yamaha says gives a richer, wider range of tone color, and there's a brace on the main tuning slide that Yamaha says focuses the sound. The bore, bell size, Monel pistons and 11B4 mouthpiece all stay the same. That makes the upgrade gentle. The horn feels familiar, and the sound gets warmer.
Yamaha also sells a YTR-3335 between the two. Its catalog describes it as a horn for players ready to move up, sharing the free-blowing feel of the YTR-2330 but with a reversed leadpipe and a single brace. You'll see fewer of them used.
Reading Yamaha model numbers
Yamaha's trumpet numbers carry a code that helps when you're scanning listings. Collector model charts read the first digit as the grade, with 1 and 2 for beginners, 3 for step-up, 4 and 5 for intermediate, 6 and 7 for professional, and 8 and 9 for the custom and Xeno horns. The second digit is the key, and 3 means B-flat. After the numbers, a G marks a gold brass bell, an S marks silver plate and II marks a second version of the same model. So a YTR-4335GS is an intermediate B-flat trumpet with a gold brass bell in silver plate.
Professional trumpets
Pro horns change the bell itself. The Bach 180S37 has a one-piece, hand-hammered number 37 bell in yellow brass and a number 25 mouthpipe, with Monel pistons, a first slide thumb saddle and an adjustable third slide stop. The Yamaha Xeno YTR-8335II has a one-piece bell too, in yellow or gold brass, on a heavyweight body. Its 2013 update brought thinner valve casings and pistons and a button on the first slide for fine-tuning resistance, and it ships with a larger 16C4 mouthpiece.
Yamaha spent ten years building prototypes for Thomas Stevens of the Los Angeles Philharmonic before launching the first Xeno in 1990, and Bach calls its 180 series the best-selling professional trumpet in the world.
When the upgrade matters
Yamaha's advice to parents is that step-up instruments use better materials and design, tend to be more durable and sound better, and that a child asking for a better instrument is a good sign worth encouraging. The practical test is whether the player practices regularly and the teacher thinks the current horn is holding them back.
Some programs skip the middle step. One high school band's published list of suggested step-up instruments names the Bach 180S37 for trumpet, a professional horn. Ask your child's teacher which way they'd go, and whether they'd also like a different mouthpiece. That same band program says high school players shouldn't still be on the small mouthpiece that came with a beginner horn.
What to check on a used student trumpet
- Red rot. Ask for a close photo of the leadpipe. Pink spots or pinholes mean the zinc has leached out of the brass, and severe cases need a new leadpipe.
- Stuck mouthpiece. A mouthpiece jammed in the receiver is common on school horns. A shop removes it with a puller, and twisting or tugging can break the braces.
- Frozen slides. Ask whether every slide pulls out by hand. A seized slide is a shop job to fold into your offer.
- Serial number. Make sure there's one stamped on the horn. School band lists treat a missing serial number as a warning sign.
What to check on a step-up trumpet
- The model stamp. On a Yamaha, look for the G in YTR-4335G or 4335GII, which marks the gold brass bell. GS means silver plate.
- The main slide brace. It should be firmly soldered at both ends. This is the part a student horn doesn't have, so it's the one to look at closely.
- Dents in the tubing. Bell rim dings matter less than creases in the tubing, which can affect intonation.
What to check on a pro trumpet
- Valve wear. Pro horns get played a lot. Valves that wobble side to side in their casings are a sign of serious wear.
- Compression. Pull a valve slide out a little, then press its valve. A clear pop means the valve is sealing well.
- Generation. On a Xeno, the button on the first slide marks the 2013 version, and the model stamp tells you which generation you have.
- Finish. Lacquer and plating wear with use, especially where the hands sit. Expect some on an older pro horn, and ask about any spots of corrosion.
Whichever level you buy, book a check-up at a brass repair shop when it arrives. For the full list of brass checks, see our used brass checklist, and if you're buying a first horn, start with our parent's guide. You can also browse all trumpets or compare the step-up and professional models.
