My friend and hero Ned Steinberger was on TV this morning talking about a new prototype bass he's designed. I had this very bass for a few gigs over the Summer to try out, and it blew me away. The bass can be played either active or passive,and the active option almost has a Neve preamp sound to my ear. The active system is charged thought the input jack and powered with a super capacitor,and a 60 second charge will get you 16 hours of playing time.No batteries to change EVER! Pretty cool! Thought y'all might enjoy.
