Thank you to the store for quality pre-sale verification. What could you expect for such a price? Curved crookedly, the naked eye can see the difference between the edge and the body of the bend. The socket cracked, it is clear that due to the incorrect manufacture of the "technological hole" attempt to solder the crack failed and the Chinese decided "it will do as it is" . About small shortcomings, with sanding and threading, I am silent. I don't know how long this thing will live, but let's hope I don't smash it to pieces in a couple of rehearsals.
P.S sound is good.
