I got one of these off Ebay when they were still marketing under the name Hysong - same people.
The bass took forever to show up - a double neck 4 string fretted and 4 string fretless.
The fit and finish was good. The wiring was silly and needed to be redone.
The fretless neck had the same side markers you put on a fretted neck which is really annoying.
Long story short I did a TON of work to it, to make it into a good bass. I slotted the fretless neck
and put in maple fret lines(they should offer this) I replaced the weak single action truss in the
fretted neck with a double action truss from Luthiers supply, and the big thing was taking that
neck to a friend's machine shop to get channels cut in through the back to install two carbon
graphite rods up against the finger board without removing it. The neck now has two "skunk stripes"
So NOW it plays and sounds pretty good. Paid $399 for the bass plus
$100 shipping - The improvements cost me another
$100 in diner feed for the machinist and the truss rod and CG rods.
The real Murphy's Law of the deal is I got this for a band I was playing in, where I was switching
between fretted and fretless a lot...The band broke up the week after it got delivered.
I got the feeling these ones on Ebay are still there becasue he ran them off when he did my
"custom order" (fretted 4 string instead of a 5 string on top)
