I had a 'karina' jazz bass copy, it was so long ago it was purchased using a different currency. I (my dad) paid £90 IRL (punts) for it. It was actually a decent bass but got batterend a bit along the way. All running repairs were carried out using non-luthier components. I remember it has a really heavy bridge and a string through body. Wehn I eventually purchased a Fender Jazz, I tried to do a Jaco job and make a lined fretless out of it. I made a complete mess of it. Pity.
