Hey, we just got a new mic for lead vocals: Sennheisser ew165G2. It is supposed to be good for minimizing feedback - it is also supposed to be really sensitive (the reviews said "I don't have to eat the mic for it to pick me up" and stuff like that).
So ... here's the problem in a nutshell: small stage, big microphone ... big feedback!
We immediately adjusted the sensitivity on the microphone. That helped a bit, but our sound guy had to max the volume as a result. We also adjusted gain and compression as much as possible and turned the acoustic amp off to the side.
I'm not sure if we are getting the feedback from the amps (which are within 5 feet of mic) or from the monitor/main placement. Our monitors are 5 feet off to either side - our mains are suspended from the ceiling only about 5-8 feet in front of the monitors.
Our platform is less than 10 feet deep (but 20+ feet wide) - there is no "back stage" or doors off to the side where we can place the amps. This puts all our musicians in a row. Left to right, it's drums (no mics/no shield), bass guitar & amp, acoustic guitar & amp, electric guitar & amp, and keys. Due to the projector screen placement, etc, keys and drums must stay where they are.
Am wondering if you all have any ideas on how to make this mic work at our church?? Would it help to do a direct box on the acoustic guitar (we used to do that). I don't have a pod or anything for the electric guitar, so that amp has to stay.
