5 string double bass

So while 5 string Double Basses are becoming more common due to the improvements they made in the setup, I figured out a really cool way we could make the Lower notes speak more clearly is w/ a "Hole in the Heart Surgery". I got that idea from a "Hole in the Heart Violin to Viola Conversion"...

So this is an interesting 5 string Fretless Acoustic-Electric Bass called 5 String Bace (Bass-Cello). Mark Zandveld came up w/ it, & it's basically a Scaled Down Electrified 5 string Double Bass that can be held like a Guitar. As you can see the neck is from an old Fender 5 String Fretless...
