Michael Manring uses this technique in the song "Diagonal Head Trauma" He "knocks" on his bass, whether it be with his fingers or palms, etc, and gets a drum-like percussive sound. My question: How does he get it to be so loud? In the video I saw, all of the knocking was as loud as the notes he was playing, but when I try it, it doesnt work out nearly as well. Does it have to do with the body mass of the Hyperbass? Because thats the only reason I can think of why this shouldnt be working for me.
