Thomann TR-4000S Bb- Trumpet

Just received this trumpet which seems to be extremely well built, with a very full and big sound, but this is only for those who want this kind of tone !
I don't know why, but I couldn't get all the info I've requested from Thomann prior ordering this trumpet, then I could have avoided to buy it and send it back, just because it's not the sound that I was looking for.
I need to say that these trumpets are excellent for those looking for a big tone, with enough core, very free blowing and responsive, with an easy upper register.
Thomann does not share all technical details of their trumpets ( bell taper, bell thickness, overall weight etc - this should be an improvement action for Thomann in the future, as their trumpets/instruments are NOT that popular as many other well known brands/models ), so I had to find out by myself.
TR-4000S has a heavyweight and a large bell ( similar to Bach 72 taper), producing a very full and big sound, very resonant, that it doesn't break if it's pushed. Upper register is easy enough, probably due to it's reversed lead pipe, but it needs more air to get the best of it :) Overall, the trumpet is very well built, with a very nice finish, very good valves from the first touch (no sticky valves, very smooth action). It feels solid in your hands, well balanced...just as any other professional trumpet on the market.
If I would have known these aspects before, I wouldn't have ordered it, and not because it is not a very good trumpet, because it really is, but not for me !
Later edit : I've decided to keep it and give it a chance - if you can get used with it, learn how to play and control it, it might be one of the best trumpets in the world for the money.

I purchased this TR 4000S along with a TR 500 s in order that we could compare them to see which might be most suitable for our youth marching band. (Kids from 8 to about 16 years)

The TR 4000 S seems well made especially bearing in mind the price. The tone is good and valve response seems fine. Reverse lead pipe is an interesting feature as are the hexagonal valve caps and buttons. This makes it an attractive looking instrument. The case is also well proportioned.

We found that adults and the older kids preferred this instrument to the TR 500 ( perhaps the slightly bigger bell and response in the upper register was influential) whilst the younger players preferred the less expensive trumpet.

Overall a very nice instrument for the price although we have opted to buy a quantity of TR 500's on price grounds, the balance of the trumpet and because of the preference of our younger membership

Eigentlich habe ich mir die Trompete nur als "Notfallinstrument" oder Zweitinstrument für "gefährlichere" Aufgtritte wie Umzüge und Bierzeltmusik besorgt, die ich nicht mit meinem Hauptinstrument (Yamahe YTR8335RGS) spielen möchte. Umso überraschter war ich, dass die 4000S der weitaus teureren Yamaha gar nicht in so viel nachsteht. Natürlich wird nicht die Leichtigkeit in Spiel und Handlich erreicht - was aber bei 400 statt 3000€ auch nie der Anspruch sein kann.

Die TR4000S spricht leicht an, bietet eine gute Tonkontrolle und alle Töne sind da, wo sie hingehören so lange man in der "normalen" Range unterwegs ist (c1-c3). Im high register bzw. der 3. Oktave tue ich mich schwer mit dem Instrument, was aber wahrscheinlich eine Kombionation aus der Instrumentqualität und meiner Gewohnheit, ein anders Instrument zu spielen, ist.
Die Maschine ist recht leichtgängig und komfortabel, ich hatte bisher keinerlei Probleme mit hängenden Ventilen und dergleichen (dafür habe ich das Yamaha Standardöl eingefüllt). Die gesamte verarbeitung ist vorbildlich, weder an Material noch an Lackierung usw. konnte ich den kleinsten Makel erkennen.

Insgesamt ein sehr ordentliches Allround-Instrument für Schüler oder Vereinsspieler.
