I buy a lot of things from Thomann, very happy with the quality and it’s rare occasions that promises and not fulfilled. but this was expensive and I was not impressed. I should have returned, in the time window, but I was on tour and missed the opportunity before I realized that it’s not optimal for brass at all and I’m still looking for a solution to reduce the Noise and sound, probably more sit for a bass drum, it’s very heavy too and hard for positioning. Needs a good quality interface to boost power. Pity.
