I have a 1500 watt PA system with huge speakes. However, I cannot get my acoustic to come loud enough to compete with the rest of the band when I mic it with my Shure Sm-57. It's definitely loud enough for a singer. Is there something that I'm missing?

Have you tried using a pre-amp or eq?

mic-> pre-amp-> eq-> mixer

pre amps help, even with a dynamic mic like 57. give it a shot

Hey, sorry to add my own off-topic question, but what's the difference between a pre-amp and an EQ. I thought the two weere the same thing, choosing which signals to boost and which to reduce before that sound gets amplified.

I believe the problem lies in the type of microphone you are using . Dynamic microphones ( SM-57 ) are great for mic'ing snare drums , guitar amps and even vocals but you need to be real close to the sound source . The sound quality drops off the farther away you get from the microphone . Condenser mic's are much better at picking up sound from a distance , which is why they are often used to record or pick up cymbals from overhead . Of course , they would also have the capability of picking up other sounds that you might not want , but I believe with proper placement you could eliminate much of that as well . With the SM-57 you need to be not more than 3-6 inches away and hold very still . The most popular method for onstage sound is to mount a pick-up inside the guitar itself or in the soundhole and then use a guitar pre-amp . Fishman makes a very good one that has a 4-band EQ along with volume , compressor , and XLR connector . It also is a DI box . I know that it means having to buy more equipment , but the end result is the freedom to move around on stage .

If I claim to be a wise man , it surely means that I don't know .

The negative of a condenser mic is that it requires phantom power (usually 48V), which means a power source, either a mixer with inbuilt phantom power or a condenser mic pre-amp.

I started with nothing - and I've still got most of it left.

A 57 is not a good mic for live acoustic guitar. You can not get it close enough to sound good without it getting in your way. You need a pickup or a condender mic; each has pros and cons, as others have mentioned. Personally, I would go for a nice pickup like the Fishman Rare Earth. If you really want to use a mic, look into small diaphragm condensers. AT 4041, AKG 391, AKG 451, or even Shure SM81 would be good candidates. All of these require phantom power, as greybeard noted.

Another option is the electret-condenser microphone which has a battery of its own .
