Can't say enough good things. I loved my dimple before because it's such a great layout and unequivocally adorable, but the addition of the dual layer foam makes it sound like... A dream. A brick. Idk. All I know is the echo is gone and all I hear is the glorious, gentle tones of pbt on brass.
Foam was a perfect fit and really easy to install. Definite improvement to sound thanks to the foam. Would recommend!
