So far I could not find a clue about the top wood but I think you hit the nail on the head!
Of course I looked a bit further into this and found that Amboyna (which is particularly from Ambon, Indonesia) seems to be one of the names of (burl) wood from the the Pterocarpus tree, also named as Padauk/Padouk (African). Looking at Padouk burl pictures this looks similar indeed. All of these woods are rated as high-quality, so I'm very pleased with yor information.
Many thanks for your kind response and kind regards,
Not sure if this belongs in this thread, but its an all wenge neck 1998 fna with a single pick up, i think it qualifies . If anyone has anymore info on these basses im all ears. I have read a fair ammount about them, but it's hard finding out much about this specific model
Beautiful! And what a nice example where the paddle head is adjusted to the new headstock, but the tuners are still straight! The cherry is so close to my '85 (?) no serial Streamer! And fretless is just so pr0n - dirty, dirty
