An integral part of Dyna-Mic’s patented feedback reduction technology is our Harp-Gasket. Now there’s no more need to spend years mastering your cupping technique. You can play with just one hand, or hands free, turn it up, and sound great!
When not being played a harmonica is almost airtight and this makes it harder for sound waves to pass through it. Our Harp-Gasket and Pro-Gaskets take this fact, and use your harmonica to essentially seal the Dyna-Mic chamber. This creates an environment for the Dyna-Mic’s element which protects it from feedback inducing frequencies.
In developing the gasket over the last three years we have found that the tighter the gasket fits your harmonica, the more volume you can get before feedback occurs. For this reason in addition to our standard Harp-Gasket that fits 80% of commercially available harmonicas, we are also offering a range of Pro-Gaskets that are tailored to fit your favorite model of harmonica like a glove.
