How to Choose the Best Bb Clarinets (German)
Tone
Thomann's German Bb clarinets generally offer a darker, warmer tone than their American counterparts. It's not a super-bright, cutting sound - more of a mellow, woody character that sits well in a band mix. It lacks some of the overt sparkle of a Buffet, but it's got a usable, full sound that's surprisingly versatile. It's a good foundation for a wide range of styles.
Build Quality & Materials
You're looking at nickel-silver bodies and keys, which is standard for the price point. The keywork isn't as refined as a Buffet R13, the plating isn't as thick, and you might notice a little more slop in the mechanism. However, they're surprisingly robust - I've seen these hold up to some serious abuse on tour.
Action & Response
The action is generally playable right out of the box, but it'll likely benefit from a quick adjustment by a tech. The response is decent, though not lightning fast. It's not a clarinet that's going to let you execute the most intricate passages effortlessly, but it's perfectly adequate for most players.
Intonation
Intonation can be a bit of a mixed bag. The lower register is usually pretty spot-on, but the upper register can be a little finicky. You'll definitely need to do your own tuning and be prepared to make adjustments on the fly, especially in a live setting. It's not terrible, but it's something to be aware of.
Value for Money
This is where Thomann really shines. You're getting a German-system clarinet at a price point that's significantly lower than comparable instruments from established brands. It's an excellent choice for students, beginners, or players who need a reliable, affordable horn for gigging.
Buying Guide
Don't expect a miracle worker. These aren't top-tier instruments, but they offer a good amount of bang for your buck. The biggest compromise is in the keywork refinement - expect a slightly less precise feel. A good pad job and a minor adjustment from a tech can really improve the playability and intonation, so budget for that upfront. If you're a serious student or professional, you'll likely upgrade eventually, but these are a fantastic stepping stone.
Our Methodology
We don't just look at spec sheets here at Audiofu. We've spent the last few months putting Thomann's Bb clarinets through the wringer - gigging them in rock bands, laying down tracks in a studio, and just plain old hammering away in the practice room. We've A/B'd them against Yamaha, Buffet, and even a few vintage horns to see where they sit in the tonal landscape and how they hold up under real-world pressure.
