"Microphone Feedback"
 
Right now, I have a Classic 30 amp, and use a Green Bullet. I like the sound I get, but feedback is killing me. I think that the mic might be the problem. No matter where I have my amp set, or where I place it (including putting it in a box) I get feedback. When I turn up in the monitors, the feedback is even worse. I think it has to do with the bullet mic and the range it takes sound from (I believe it unidirectional). What kind of my would work better? Would a sm58 isolate the harp and take less sound from around me, ie. reduce feedback form the objects around me? Help!!!

Dude, welcome to the world of playing amplified harmonica. There is no quick easy answer to your problem. This is why a lot of us aging players end up playing through the PA system at gigs. MIcrophones are not made to be played through amps nor are they made to be cupped with your hands. Again, welcome to the world of playing amplified harmonica. I play with a relatively clean ball mic through a fairly big clean 130 watt amp. I don't get exactly the sound I would like "live", but I am always heard. I don't "mic" the amp, it is loud enough by itself.

Here's a couple of posts that may or may not help-

WHAT I USE:

"AVOIDING FEEDBACK; HOW TO GET AN OVERDRIVEN SOUND" 8/8/03
http://www.harmonicalessons.com/members/dcforum/DCForumID4/56.html#1

Also, take a look around the "Mic and Amps" section and see if anything in there is helpful-

Let us know how it goes.

Play on,

Dave,

Can you tell me more about the Barcus-Berry pickup? Also, do you use anything to control volume on stage?

I have the amp miced, and the only effects on it are the stomp box that lets me change channels and use reverb. The feedback I am getting is coming from the monitors when I turn up my mic. So, I can't get enough volume through the pa. Is this because I am using a Green Bullet? Would a high impedance mic like the MB 1000L let me turn up in the monitors? I already have an sm58 and sm57, would one of those with an impedance converter work?

Also, I am going to try a couple of equalizers out. That might help with the board. I really like the sound I get out of the Classic 30, but even with the band turned down I am getting a lot of feedback through the monitors (much more then through my amp).

Thanks Dave, you're the best!

"Can you tell me more about the Barcus-Berry pickup? Also, do you use anything to control volume on stage?"

I don't use the pickup on stage because on some of my songs I use more than one harmonica and I can't switch them quickly enough with the velcro-type pickup attachment on. On the mic I use onstage, it has an "On-Off" switch. I will use nothing onstage because when I won't the mic off for feedback reasons, I want it all the off immediately. Volume controls can take extra time to switch off. If you wanted to use the pick-up onstage, I would consider getting a standard volume pedal or "on-off" foot swtich to kill the sound when needed. They work just fine.

"The feedback I am getting is coming from the monitors when I turn up my mic."

Don't go through the monitors, you're just asking for feedback problems. Get a bigger amp or put it on a chair or place it facing you on stage (like the monitor placement).

If you want to use a SM 57 or 58, use it directly through the board, the amp is causing all the feedback problems. Make sure your mic through the PA has a built-in "on-off" switch for when you start to feedback. Remember, if you are putting your hands around a microphone, it is going to want to feed back. Welcome to the world of harmonica.

"Also, I am going to try a couple of equalizers out."

They do nothing except EQ out the good sound frequencies on your sound. That is, they take out the good sounding mid-range tones which tend to feed back. When the EQ has removed all the feedback frequencies, you've just lowered your entire volume. You can do that at the amp with the master volume. Email me directly if you have more questions about this.

Play on,
Webmaster
