Now this is the easiest way to get your instrument broken-in/seasoned, by far! Guitar, violin, mandolin, whatever instrument you want. Wether it's new or needs to get losened for a gig, this is the tool to do it with. Basically, all you have to do is put the two circular speakers on your instrument and play music on them. (I personally believe you best play the music you're going to play on the instrument. No scientific proof for that theory though ....)
Neat box, protective padding, easy to operate, fun to do, fit for any instrument that has tonewoods.
What else could you wish for?
