I bought this, because i wanted to try a synthetic reed and i was immediately convinced, about it, when i read that it is the darkest reed.
This reed looks plastic but has a cover up from hemp or something. The sound is really bright and not at all dark.
I play jazz and have a philtone metal mouthpiece and in the past, I've tried a VENN DAddario synthetic reed, which played ok but it was still on the bright side, though with a lot of darkness, but you could still tell its synthetic. I was hoping that the hemp fiberreed would be darker, but it is not... If you want a dark synthetic reed the closest youll get is with a venn. I think that synthetic reeds are for more modern music tastes and if you play jazz then, in my opinion, never buy a synthetic reed.
If you are looking for a synthetic reed and you want a bright sound then this reed is awesome for you! The response is brilliant and its really easy to play in all registers. You might want to try a stronger reed than the one you play though because it seems to be a bit soft.
