|

I've seen this 'sound reflectors' used, that wrap around or somehow mount on a mic stand for say some SM57's. I can't figure out the right name or search terms to try and find some for sale.
Would love any recommendations and/or direct links to where they can be purchased. _________________ "Music is like candy, you throw the (w)rappers away." |

Here's the one I've seen that got the most attention back in the day.

One caveat - I've had at least two sound guys at live venues tell me that the ones that fit over a microphone do terrible things to the sound. I'm no expert, but it has something to do with blocking the ports that enable cardioid pattern mics to block sounds from the rear and sides - it turns your cardioid into an omni. Sound guys have told me they hate sound shields for this reason.
Just something to consider. _________________ Yamaha 8310Z trumpet

Actually, I am an expert in this (decades of experience as a live sound engineer), and you're right.
The baffle can make a directional microphone behave like an omnidirectional microphone if the microphone is placed in the middle of the hole in the baffle. This is a very bad idea, since the directional characteristics are critical for preventing "ringing", aka speaker feedback squealing.
If the microphone is not actually in the hole, then you still have to deal with the crazy things that happen to the frequency response when you put a microphone too close to a reflective surface (PZM mics are an exception). In fact, the owners manuals for SM57 and SM58 microphones specifically advise against it (although most people don't bother to read those things). As general rule of thumb, the nearest reflective surface to your microphone should be at least three times as far away as your trumpet bell is to your microphone.
I no longer do gigs, as a trumpet player or a sound engineer, where the volume levels are high enough that anyone would want to use a reflector. If you make your living in a very loud band, you do what you have to do; I understand that. But the sound of your trumpet in the mix will be seriously compromised. When it's too loud, something has to give, and a trumpet that sounds like a kazoo can be the best option if it allows the player to hear himself. In-ear monitors are a much better solution, but of course there are significant costs, in money and otherwise. _________________ '75 Bach Strad 180ML/37

Thank you both for this highly valuable information. I had no idea that was a potential problem. Glad to know of it before I made a purchase decision, thank you. _________________ "Music is like candy, you throw the (w)rappers away." |

I used one of the “Soundback” reflectors for a while. They definitely do help player feedback, but I felt as if using one was giving more control of my balance and projection to the sound guy than I was comfortable with.
If you have a skilled sound guy, great, but most of us have certainly run into those who are not. I worked with one guy in particular (who was also a guitar player) who obviously did not care for a bright, lead trumpet sound, so he would bury me in the mix. Very frustrating, especially since I had to work with the guy almost weekly.
