Neo-Buster Soundhole Pickup & Feedback Buster

 

 

 

The Neo-Buster combines Fishman’s popular Neo-D Single Coil pickup with a feedback-fighting soundhole cover for superior acoustic tone in any performance setting. The flexible integrated soundhole cover reduces the build-up of energy inside the soundhole that often leads to uncontrollable “howling” during high volume situations.

 

 

This single coil magnetic soundhole pickup shares the same neodymium magnet structure as the award winning Rare Earth® pickup for exceptional string balance and sparkling acoustic clarity. Its low profile, high impedance design requires no battery and is easy to install in most standard acoustic guitars with no alterations.

Not really snake oil but a poor explanation. Soundhole covers DO control feedback. Energy doesn't really "build up" inside the soundhole.

 

What actually happens is that covering the soundhole creates more or less a sealed box. Since the air is trapped inside the guitar, the soundboard is less free to move up and down. When it moves inward, pressure increases inside the guitar. When it moves out, a slight vacuum is created. This static state keeps the soundboard from moving as much.

 

 

BTW this is the true function of soundholes. It's not to provide a place to "let the sound out" .....It's there to free up the passage of air in and out of the guitar so the soundboard can move more freely. It's the soundboard vibrations that you hear pushing air back and forth like a speaker diaphragm. This is true of standard folk guitars, classical guitars AND archtop acoustics.

Not me, based on the portions you emphasized. A mag pickup can indeed reproduce the sound of an acoustic guitar so I don't see the issue.
