Thx for all the advices so far!
A lot of different opinions, but all great!
This attachment is a sample from a song wich contains a kind of sound I like and may suit the arrangments I will record. I judge them as bright sound. Am I right?
As a mentionate before we will overdub all the parts.
First take will be:
Alto Sax + Trumpet + Trombone
sacond take (overdub):
Tenor or Baritone + Trumpet (or flugel) + Trombone
The guys plays great togheter, they are top session players. Actually the sax and the trumpet are brothers... so you can imagine. (I hope this helps my debut

)
The only mic that maybe I can borrow is another TLM 103. In case to go all condenser, that helps?
