You can find them everywhere, but they are
ALWAYS attached to a MM bass body. If you
just wanna "try fretless", get you a 3rd party
neck and "try fretless". EBMM necks have no
graphite inserts, so you won't lose anything
on that score. And you won't wind up with a
2nd rate fret job, so thaz also not a problem.
Better still, you might even wind up with an
ebony FB which is not offered on regular MM
FL necks. And .... you might be able to order
your neck with lightweight tuners [Hipshot or
such] which are not gonna be on any used
MM instruments right now [later, tho ... ].
