It requires no electricity or batteries and it can provide personal amplification on any guitar or bass. Best of all, you can carry it in your pocket.

The new Noggin Rockers amp is a stethoscope-like device that attaches to the surface of a guitar or bass. The sound from the instrument is then sent up to a pair of soft-gel ear buds using physics alone—no electricity or batteries required.

User can adjust volume and tone by loosening or tightening the Noggin Rockers’ diaphragm retaining ring. Moving it closer makes the sound louder.
