Fettester - If the MFX sonic was reversed engineered, how come the ridges are wrong at the end of the main crackle body? We have seen pictures on a previous thread from RubberToe, who looked after & still (I believe) has the prop that they were completely different in shape. There is also a close-up of the paint. The colour is there for all to see. I can't comment on the head, only to say that when I had mine the colour was very different. If it wasn't cast but polished, or whatever, why wasn't the rest of the body metal bits treated the same to give a consistant look?
I'm not denying that MFx didn't have access to the original prop, but somewhere down the line thing were changed, so it doesn't make it 100% SA. Big mystery is why the changes were made? Shame really.
