Hi Petrus, the IB-6 comes with a spalted maple top not flame as shown in that picture so not sure if you would want to destroy what could look very cool in it's own right. If you sculptured the rounded edges it could also end up with a similar look. Those control knobs look like they are wooden and probably turned on a lathe or decent sized bits of dowel sanded down to size.
All up, quite an ambitious project and wish you lots of luck.
