As 'fake' means something that isn't what is described to be, then yes they are fake. Engineered is just another way of describing it. The bubinga isn't bubinga, the ebony isn't ebony and the figured maples aren't maple. They're sustainable, rapid growth, tropical hardwoods which are stained, then veneered and laminated into blocks, then cut at the correct angles to give the patterns needed.
All the madrone, tribals and striped finishes are also made this way, it's only the masserbirke, mahogany and one or two others that are the real wood veneers like thet used to use.
Sonor will happily (and correctly) tell you this, they're in no way dishonest about it, and that it's better for the environment, mostly cheaper, less wasteful and more consistent plus they can get any any colour/design they choose.
Premier and DW, to name but two, still use the real wood veneers.
