The Yaba X is a portable surface vibration speaker that will amplify on anything
Possibly the worst part about being a traveling musician is lugging all of your equipment around. So long as you’re not playing to a stadium, you really don’t need an entire sound system. However, you do want to be loud enough for others to hear you. If you don’t have the money for an amp, then you’re going to want to find an alternative that will allow your song to carry through the streets.
The Yaba X is a vibration speaker that also can act as a guitar amp. It is one portable package that you can place on all matter of objects, and the richness and strength of the sound will change depending on what the item is made of. This will play nicely with pretty much anything that has a 3.5mm jack. This means your smartphone, tablet, or even laptop can be used. It has 3 bicolor LED lights that will indicate what the device is up to, and you only need to hit the button to power it up.
Paying $90 will get you the Yaba X, three feet of audio cable, 1/4” to 3.5mm adapter, a 3-foot USB charging cable, a carrying case, and of course, a manual. It will last for about eight hours on one charge, and is small enough to be tossed in your bag. As a bass player, this would be great for practicing as it’s always a bit rough to hear the notes aside from differentiating one rumble from another as a pitch.
