Ya know Dino, you seem to just be a stirrer of... well, nevermind. In the past, people have brought up these same arguments about Perry, and quite frankly, every time Perry has "won" the argument. In my opinion, Perry isn't arrogant at all. I'm not going to launch into a big discussion about this, though. If we could only all learn to think for ourselves and/or do a little bit of independant research...
Marketing is telling people WHAT you have. TRADE SECRETS are the methods by which you produced a product. Pickup manufacturers can MARKET a pickup by showing people charts and graphs showing the frequency response, etc of the pickup, but they don't have to tell people HOW the developed a pickup to those specifications (coil wire gauge used, number of wraps, etc).
As for the research thing, wouldn't it be so much simpler if things either worked or they didn't? Sadly, almost nothing in life is such. Case in point: Just look at wood combinations. The "either it works or it doesn't" theory kinda falls apart there, wouldn't you say?
