This Startone trombone is a fantastic entry point for students or players on a tight budget. The ABS construction keeps it incredibly light and easy to manage, while the Bb/F keys provide a surprising amount of flexibility.

- Bb/F configuration expands range and versatility for players
- Includes a soft gig bag for convenient transport and storage
Cons
- ABS plastic won't offer the tonal complexity of brass

How to choose the best tenor trombones with F-Attachment
Tone & Response
This isn't about 'good' or 'bad' tone, but about the character. Are we talking a warm, dark sound suited for ballads, or a brighter, more projecting tone for big band? The best horns in this price range will still offer decent sustain and a relatively quick response to articulation.
Valve Slide Action
The F-attachment valve slide needs to be smooth. Sticking or sluggish action makes playing difficult and affects intonation. A little oil goes a long way, but the slide's build quality is crucial here - cheaper horns often have slides that require constant maintenance.
Bell Flare & Material
The bell's size and material (usually brass) directly impact the horn's projection and tonal color. A wider flare generally means more volume and a richer low-end thump, which is great for cutting through a loud ensemble. Don't expect hand-hammered bells at this price point, though.
Slide Stability & Intonation
How well does the slide stay in tune across the range? Budget horns can sometimes have intonation issues, especially in the upper register. This isn't always fixable, but it's something to listen for carefully.
Construction & Durability
Gigs aren't gentle. You need a horn that can handle the bumps and scrapes. Look for solid construction, even if it means a slightly heavier instrument. Cheap plating will wear off quickly, but that's a cosmetic issue, not a functional one - unless it leads to corrosion.
Buying guide
So, you're looking for a tenor trombone with an F-attachment without breaking the bank? It's a common quest, and thankfully, you've got options. That extra F-attachment opens up a wider range and gives you more versatility in different musical settings, from jazz bands to orchestral gigs - but it also adds to the cost. Let's break down the best bang-for-your-buck trombones under $800, keeping in mind what you really need for gigging and recording.
At this price point, expect some compromises. You won't get a hand-spun bell or a perfectly flawless finish. The biggest trade-offs are usually in the slide's smoothness and the overall consistency of intonation.
Prioritize a horn that feels comfortable in your hands and has a decent response - you can always tweak intonation later, but a poor action is a constant frustration.

Questions
Is a used horn a better option than a new one at this price?
Absolutely. You can often find higher-end horns from a few years ago within your budget. Just be sure to inspect it carefully for dents, cracks, and slide wear.
What's the difference between yellow brass and red brass?
Yellow brass is brighter and more responsive, while red brass is darker and warmer. It's a subtle difference, and personal preference plays a big role. Try both if you can.
I'm a beginner. Does the F-attachment matter?
It's not essential for beginners, but it's a good investment if you plan to play a variety of music. It'll expand your range and give you more flexibility later on.
How often should I oil my slide?
At least once a week, more often if you're playing a lot. A dry slide will get sticky and affect your intonation.
Can I expect a horn in this price range to sound as good as a professional model?
No. Professional horns have better materials, tighter tolerances, and more refined craftsmanship. But a well-chosen horn under $800 can still be a very capable instrument for gigging and recording.
