First of all, I am beginner drummer that joined a band that already goes live from time to time and has its own great author songs. So what's happened? These guys jam in a penthouse apartment, which is approx 150 sq. meters. Here is a pic of its "working zone", which takes 1/4 of the whole room area:
It also has hand-made istanbul cymbals set, which sounds amazing in drum room. Here comes the trouble. From what I heard while playing on the set in this room, drums (some well-tuned) sound bad and cymbals are just disgusting. As far as I understood, room acoustics is an issue here. How can I try to enhance the way the whole thing sounds here?
