Saxophones Buzzing noise with microphone

[Tommy Ng]

Hi all,

Hope someone can help. I recently bought a NUX B-6 wireless microphone. I'm experiencing a buzzing noise when playing middle G through C# on my tenor saxophone while using the microphone. I couldn't hear any such noise when playing without the mic.

The noise only appears when the mic is pointing at the bell, the closer the mic is to the bell the louder the buzzing noise is. There is no such noise when I point the mic at the G to B key holes (playing middle G to C# at the same time). It only happens with middle G to C#, upper register is fine.

Any advice would be appreciated. Cheers.

Is the buzzing coming direct from the horn?

Or does appear in the feed from the mic?

If it's a mechanical vibration... are you sure you're clipping the mic to the bell securely?

A thing I've notice with the Nux6 is that when you join the mic to the transmitter you have to push fairly hard to get the jack to sit deeply enough to allow the securing ring to screw into place... any looseness there might cause an electrical or possibly a mechanical buzz

I'd guess something's not 100% secured and is vibrating, making a stick-slip kind of noise.

Playing double bass one day, there was this horrible vibrating graunching kind of noise, and it just kept getting worse and worse. Amp, no amp, same. I made it through the gig, went home - it turned out it was my bow quiver, attached to the tailpiece just tight enough to generate a stick-slip noise, but not tight enough to keep it from happening. Slick surfaces against slick surfaces can often do this. Those of us who had to drive mid 70s cars will remember the infuriating squeaks and chirps from the snap-fit plastic dashboard parts, that you'd have to wedge a little folded piece of paper towel in the crack to make quiet.

Fixings, like for example clamps, can have a resonant frequency - a range they vibrate strongly with; and outside of which they don't.
Big / heavy things are likely to resonate with low notes and smaller things with higher notes.
Intuitively, middle C and up are highish; a spoon in a cup size? Maybe the plastic cover of something not properly locked in? Is there some fixing or object of that order near by?
