Awesome neck thru body handmade bass by the great luthier Jerzy Drozd at his shop in Barcelona. This is a Mastery model with a 7 piece neck for more stability. Converted to fretless by a luthier afterwards.
Apart from the excellent noiseless singlecoil handmade pickups there's also an RMC piezo system that can be blended with the magnetics. The Aguilar OBP-3 preamp will allow you to get just any sound you can think of.
This is a used bass (about 11 years old) but it is in great condition.
