Sound Damper
I copied this idea from the Raffin mini 20. My wife began getting irritated due to my playing the Organ in the house. I sometimes will play it for ½ hour to 1 hour at times. It works quite well, cuts the sound down tremendously, without too much distortion.
I picked up some Plexiglas sheet and made the following damper. It's a pressure fit to the organ (remove the front of the organ 1st). If you would like dimensions, please email me at chscable@mac.com
