I've been asked what type of wood this bass is made of and I can't say for sure. It's a 99 Thumb 5 Bolt On. I understand that some time during 1999 Warwick switched woods of the body/neck/fretboard from Bubinga/Wenge/Wenge to Ovangkol/Ovangkol/Wenge.
The manual from 1999 says it is Bubinga but I'm not sure if that is the final word. The body and the neck appear to be different types of wood which, I think, would also support the idea that it is Buginga since, theoretically, the body and back of the neck would match better if it was made after the switch to Ovangkol. Or at least that's my theory. I've found conflicting info online though that makes me wonder.
