Thomann SL-35 Alto Trombone

Use: To get a different voice from my main horn (bass trombone) for homemade videos and such

The SL-39's quality is good for this price range. The slide is not perfect and requires decent amount of slide lubricant to get it moving acceptably, although still around 7/10. However, the overall build quality is good, an the assembly is solid and clean. It is quite front-heavy, which is not so good for any trombone, but not that severe and I think I will try fix it myself with homemade solution (like taped weight).

I cannot say much about the intonation and sound, since this is my first alto experience. However, it does sound like ones I have heard others played before, and the intonation quirks, while present, are easy to adapt to. The case is also compact and lightweight. Overall I am satisfied with the purchase.

***I test it with GEWA 7C mouthpiece, not the one that came with the horn.

Pros: Good overall build quality, good value for price, nice case and supplements
Cons: Slide is not perfect, a bit front heavy

I am a Trombonist living in South Korea
I had an important test for alto trombone, and that time I didn't have my instrument so I buy this one
Shortly saying, I was satisfied for this.

The feature of the instrument looks good
The sound was brighter than other professional instruments, but I think it is advantage. It sounds like an alto voice.
It has a little problems with intonations espacially for high register, but It is affordable for me.

If any students wants to start learning on alto, I will defenitly recommend this one, and It sounds like real alto voice.
