Thanks for the input. I have indeed bought something similar.
It works, but the noise level at the end of the day is not super satisfying. I am not an expert in microphones, but I thought the E835 would produce something a bit better. Possibly I am missing some understanding for getting better results. I think I remember an older post about microphones for wind instruments in the forum. I'll try to look it up to check if there is not something that could help me there.
Thanks to everyone for your help !
