I'm glad you had fun with it. Basically, it is just a fun distracting exorcise. I, for some reason, love this guitar, Greeny, I don't know exactly what it is, but of all the rock guitars that have made so much music we know, this one really fascinates me. I think it has something to do with the songs Peter Green used the guitar on and the history of Peter Green himself. Of all the guitar player stories I know, his strikes a chord with me...pun intended. 

So, what I was trying to do with the videos was to show people playing Greeny and try to find some videos where it is easy to see what pick-up we are hearing. There is a three way switch you can see on the guitar (the one in the white circle), when it is switched upward, the guitar is switched to the neck position, the pick-up closest to the neck of the guitar. When it is switched downward we are hearing the bridge pick-up, the one nearest the bridge of the guitar, the metal bar toward the back of the guitar. If the switch is in the middle position, basically sticking straight out, we are hearing both pick-ups together. 

So, a guitar player will switch between these positions to get a certain tone for whatever they are playing. Obviously, watching Hammett play he gravitates toward the bridge pick-up when he is playing a solo. You can see he has the three way switch flipped downward, indicating he is using the bridge pick-up.

The other thing about Greeny is the neck pick-up is upside down and wired incorrectly, which may have been down on purpose. It causes the two pick-ups to be slightly out of sync with each other when the three way switch is set right in the middle, so it is using both pick-ups at the same time. 

It's probably way more than you wanted to know, but I think if you listen closely to the clips you can hear the differences. I also just think that this particular guitar has a unique sound...I mean, it does to me. Something about it is somewhat odd, or I guess very discernable. It seems somewhat unique. Now, maybe I am imagining that, I don't know, that is kind of why I was posting these. The thing is, I think you have to listen to a lot of clips of the guitar being played, then listen to some other guitars being played to really recognize the difference in tone. 

Kirk Hammett claims that the best sounding Gibson Les Paul guitars are ones that have had their neck broken and repaired. Now, I have no idea if that is true or imagined by him. Maybe the best set-up Les Paul guitars that he has played all have had their necks broken at one time and so he has that impression. When he said this I found it odd, but due to the way the headstock on a Les Paul bends back, neck breaks or snapping off the headstock is a common injury to this style guitar. 

I'm off on a long tangent about guitars but David can probably comment, he's played a lot more guitars than I have over the years. I basically think that it is almost like have a pet that you really connect with, in that some people deeply connect with an animal, and people will deeply connect with an instrument.
