Hand made bass by the Spanish brand Weisse Hügel based in Barcelona.
This small brands produces a very limited number of guitars and basses that sport some really innovative specs and smart solutions.
It's a used bass but it's in very good condition. Just a few minor scratches.
This model is named Altehorn Drei Bass and it comes with three (drei) pickups. The main two are Delano made in Germany and the middle pickup is a US made Bartolini. Controls are Volume, Tone, 3 band EQ and 3 inidivual On-Off switches for the pickups. Lots of possibilities on tap and great sound. Passive mode is achieved by pulling the Volume pot.
The neck is made from carbon fiber and the fingerboard is phenolic. Really stable neck but there's a truss rod too so you can get your favorite action easily. Top class hardware too.
The low B is excellent, by the way.
This is not a light bass at all but using a wide padded strap will do the trick.
