Perfect! I bought this mic to my trumpet for use in acoustically difficult acoustic conditions / to avoid acoustic feedback (which I sometimes get when I play with ordinary kondesator mic.) I mounted my Rumberger mic on the tuning slide. The result was fantastic. I was initially going to use the mic. guitar effects (distrutionwa-wa ..) but also the pure acoustic sound is picked up very well. Check my website .. ********. I really recommend Runbergermik. Also for brass instruments. (The marnadsförs the most woodwinds). For trombone can be put in the nozzle. There is also a basson player who drilled hole in her nice expensive Hackel Basson for a Round Berger mic. With absolutely fantastic result. No problem to use the instrument "purely acoustic" by mic. this "sleeve".
