Warning: This episode contains ribbon cables, robotic component insertion and wave soldering. ..
I've seen several of these and often ask myself "where is OSHA?".
"How it's made" is a cool show, but very often the eposides are not about "how something is "made"...but rather "How it's Assembled" which, to me, is not nearly as interesting. The amp episode was one such example.
Episodes on, say, "how glass is made"....that was cool!
They have an electric guitar episode with Godin that's quite interesting. Also a pedal steel guitar one.
