Invented and created by Mostart, the Soundshaper is a unique instrument in that it can tap into any musical sound or frequency. He even managed to tap into the frequency of ink, as in the episode Back by Unpopular Demand. Mo can also sit on the Soundshaper and ride around in sound clashes. He usually smacks it with his hands like a drum but he also uses his fingers like with a keyboard. It's very versatile.
