Do you know where can I buy these rounded Bartolini pickups? Model\number of this p\u? Usually seen on Zon basses..
Don't have a clue. Wouldn't be surprised if Zon has used more than one Bart pup that shape - they may be made for Zon or standard issue. I would contact Zon and go from there. The Bart site has dimensions of their pups including the radius. If you don't see it there you might contact a Bart distributor like Bestbassgear. Bart hasn't made a lot of radiused pups to my knowledge.
That's the Bart RU pickup. They fit older Ibanez and the Tobias Classic 6 stringers. AFIK Bartolini does not make these anymore, and they are very hard to find last time I looked around. Post if Bart has replacements, I'd like a set.
The RU is the 6-string model, the RT is the 5-string model, according to the Bartolini pickup spec sheet. My '98 Tobias Killer B-5 had them and also my '94 Classic 5. EG
