+ The most: the single grain of bach, warmth and "opening" of sound on this model Bb.
Veneer of good quality. Pistons irrprochables.
+ Is a detail, but no key to clear the water on the third slide (the price l. ..) instead of a Bach to a slide prfer simple (not necessarily the more convenient).
Trumpet + excellent craftsmanship alone, mostly for the orchestra. For jazz, even when the models prfere + matte (varnish dvernies sand ...). To use a horn section, report emission / rponse perfect.
After all it is as good (and possibly be more the trumpet ^ ^), depending primarily on the musician.
