My version of the passive cell phone amplifier. I like the sound. It's not much louder, but it is enhanced, almost like reverb.

Very nice Hairy, but I am telling the guys in turning you are making flat stuff.

very clever wit the f-holes!
Have you tried it with a closed back? I almost think that would enhance the sound even further

You play music on the phone, this affects the sound. It's like an echo chamber.
