Hey Tim, good to hear you are doing better.
The Hot Live Wires are pretty cool IMHO. They are extremely high in output and did hit the front end of my amps pretty hard. The volume off of the LW-HS set was smular to my Distortion set. Because of their shape they don't sound like a humbucker but more like a very warm and hot single coil. Under gain they sounded incredible.
Clean they are also very nice but it's helpful to have an amp with a lot of headroom. They are very "Strat" sounding but they are warmer than true siingle coils. You won't get as much of the bright spank out of them that you would out of say an SSL-1 set but they are very believeable as far as single coil tone goes.
Can't help you with the loaded pickguard thing. The LW-HS set comes with the proper pots and output jack and I found the install easy enough. It might be worth your while to get a seperate guard and 5 way switch so that if you decide change back, the install will go easier.
