Leon!! I love it!! I tip my hat to you sir. Great playing and great tone! Thank you so much. As said, I've been checking out a lot of You Tube clips with this guitar and in my VERY humble opinion (just going by the sound) I think it's a very underrated guitar. You said the neck on yours is narrow but with the newer ones some have said the neck has some real girth to it. Others have said the pickups are very unique sounding. According to Guild, both pickups use Alnico 2 magnets and they are a low wind. Bridge is 7.00K and the neck is 7.10K.Can't speak to reissues, but I had an original for years. It was a great sounding and playing guitar...but the neck was just too narrow for me to ever feel quite at home on it. Also the original wiring/tone circuit was awful (very low value pots IIRC). I replaced it with standard 500K pots and tone caps and that made a big improvement.
Here are a couple videos I did with it years ago:
