Abstract
A feedback eliminating device for acoustical instruments is designed to be used with in-hole amplification devices, without the need to modify either the instrument or the amplification device. The device is preferably in the form of a two-piece cover for the sound hole of an acoustical instrument. Used in conjunction with an in-hole amplification device, the device completely covers the sound hole of an acoustical instrument.
