Cool guitar - I've got one in orange sparkle, I'll try to find a pic.
I find the Z coils bright, but great sounding. There are 2 coils, each under 3 strings, reverse wound. So in a sense, it is a humbucker, but because each coil is under a smaller length of string it really sounds like a single coil. Leo worked on a similar design with Fender in the 60's, but really nailed it at G&L.
The bender is cool, but I never really got the hang of it...any tips would be appreciated!! I put big bends nut sauce in the tube that goes through the asddle, and that keeps it in tune...
