How would you explain that all axial components are bent in consistent directions and cut with the same length, while non-axial components such transistors leads are not bent at all. Also manually adjusting all color-coded resistors in the same direction is quite an achievement;-)
Look no one would really care as auto-insertion is certainly a more reliable and efficient process. But that doesn't make it an all hand-assembled product.
I am sure you are aware that your listed ROHS exemptions don't really apply to and are not in the spirit of our consumer electronic industry unless you consider synthesizers part of the EADS (European Aeronautic Defence And Space) industry.

But putting the law and directives aside, why would you use leaded solder when there are less toxic solutions available?

Alignment of color-coded resistors in the same direction would hardly be a conspiracy–it was taught to me that way, as it makes it easier when checking your own, hand-built work!
But it might also be worth asking whether auto-insertion was part of the Norlin production processes back in the 1970s–and I might guess that it was, as it was also the case for Gibson–so "handcrafted" might still be as equally appropriate (or not) now as it was then.
As for Pb–where leaded solder is original specification at point of manufacture (largely applicable for nearly everything built prior to July 2006, and still the case in many parts of the world), it IS the appropriate choice, full stop, with the usual counter measures taken to mitigate employee exposure. Mixing of solder types is to be avoided in older products, for reasons of contamination (in both directions), and it is IMHO sensible that Moog, for example, physically segregates its leaded repair and rework from the rest of (RoHS-compliant) production.
For new PCB designs, lead-free sourcing / PCB layout / manufacturing is the way to go–which I believe we can agree upon. There's well over ten years' worth of expertise, which should be sufficient.
