{"product_id":"stradivarius-trombone","title":"Bach Stradivarius 42A Professional Trombone","description":"\u003ch2\u003eThe Trombone That's Been Setting the Standard for Generations\u003c\/h2\u003e\n\u003cp\u003eThere's a reason you see the Bach Stradivarius 42A on virtually every professional orchestral stage around the world. This isn't a matter of tradition for tradition's sake — it's a matter of what actually works. The 42A delivers a combination of projection, response, and tonal depth that serious trombonists keep coming back to, year after year.\u003c\/p\u003e\n\u003cp\u003eAt the heart of it is an 8-1\/2\" one-piece hand-hammered yellow brass bell — the kind of construction that takes real craftsmanship and produces a full, resonant sound with plenty of presence in a large hall. Pair that with a .547\" large bore and you've got the airflow and dynamic range you need to cut through an orchestra or carry a solo line with confidence.\u003c\/p\u003e\n\u003cp\u003eWhat really sets the 42A apart from its siblings in the Bach 42 family is the patented Hagmann valve. If you've ever fought back pressure when engaging the F attachment on a traditional rotor, you'll notice the difference immediately. The René Hagmann Free Flow™ system is designed to let air move more freely through the valve section, giving you a more balanced, open feel whether you're in Bb or F.\u003c\/p\u003e\n\n\u003ch2\u003eThe Hagmann Valve: Why It Matters\u003c\/h2\u003e\n\u003cp\u003eThe Hagmann valve isn't just a marketing point — it's a Swiss-engineered solution to one of the most common complaints trombonists have about F-attachment horns. Traditional rotary valves can create a noticeable resistance spike when engaged, disrupting the evenness of your airstream. The Hagmann Free Flow™ design addresses that directly, allowing for a more consistent, open response across all registers.\u003c\/p\u003e\n\u003cp\u003eCombined with the open wrap F attachment, the tubing path stays less convoluted than a traditional closed wrap, which reduces resistance further. The result is an instrument that feels more consistent whether you're navigating the lower ranges or crossing between registers in fast passages.\u003c\/p\u003e\n\n\u003ch2\u003eSlide and Build Quality\u003c\/h2\u003e\n\u003cp\u003eThe handslide is where you'll feel the day-to-day playability of any trombone. The 42A uses chrome-plated nickel silver inner handslide tubes paired with a yellow brass outer slide and nickel silver handgrip — a combination that balances smooth, responsive action with durability. It's the kind of slide setup that rewards good technique and doesn't fight you when you need speed.\u003c\/p\u003e\n\u003cp\u003eThe clear lacquer finish does more than protect the brass — it adds a subtle warmth to the overall sound, letting the natural character of the yellow brass come through without the brightness that a bare or silver-plated surface might introduce.\u003c\/p\u003e\n\n\u003ch2\u003eWho Is This Trombone For?\u003c\/h2\u003e\n\u003cp\u003eThe Bach 42A is built for the serious player — the conservatory student stepping into their first professional-grade horn, the orchestral trombonist who needs to match section sound, or the versatile gigging player who wants one horn that can handle symphonic repertoire, solo work, and everything in between. If you've been playing on a student or intermediate horn and you're ready for a real step up, the 42A is the kind of instrument that will grow with you for years.\u003c\/p\u003e\n\u003cp\u003eThis is a professional trombone in every sense of the word, built by craftspeople who have been making these instruments the same way for a very long time — because what they've been doing works.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Features:\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstrument Type:\u003c\/strong\u003e Tenor trombone with open wrap F attachment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey:\u003c\/strong\u003e Bb\/F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Size:\u003c\/strong\u003e .547\" large bore\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBell:\u003c\/strong\u003e 8-1\/2\" one-piece hand-hammered yellow brass bell\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve System:\u003c\/strong\u003e Patented René Hagmann Free Flow™ rotary valve — reduces back pressure for an open, balanced feel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eF Attachment:\u003c\/strong\u003e Open wrap design for less resistance and more fluid slide movement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Handslide:\u003c\/strong\u003e Chrome-plated nickel silver tubes for smooth, quick action\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Slide:\u003c\/strong\u003e Yellow brass with nickel silver handgrip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Clear lacquer — adds subtle warmth to the overall sound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIdeal For:\u003c\/strong\u003e Symphonic and solo performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Bach\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e Stradivarius 42A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e 42A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/p\u003e\n\n\u003cp\u003eSince 1872, C.A.
