Sound Booster - Powerful!
A powerful sound booster for musical instruments using a rotary valve.
As shown in the example, open the rotary valve cap, place the booster, and then close the cap.
The cap will not close completely, but this is normal.
The difference from other sound boosters I am also selling is that this one produces a powerful, deep resonance.
Changing the valve you insert it into will alter the sound.
It might sound unbelievable, but some customers have repurchased it, so I am confident that you will feel some kind of effect. Please give it a try.
*Please note that the perceived effect may vary from person to person.
