For those who aren't familiar with this, Joey DeMaio is the bassist of Manowar. I'm having a hard time finding a good photo of his 'Demon II' bass, but you can see it in many youtube videos.
It's an instrument loosely based on the Rickenbacker 4001, but with a smaller body, four super hot pickups, one volume control, no tone controls, twin outputs (like the rick) and an ultra thin carbon fibre neck. The neck is the same width all the way down. The strings are very close together, and the instrument is not meant to be played fingerstyle.
Tone wise, it's naturally lacking some of the lower end of the spectrum, as it's not designed for thick strings. It's definitely aimed more at bass notes, as opposed to frequencies.
I'm sure everybody here would like to at least try out such an instrument, but could anyone see themselves using one on a regular basis?
