On this page I have some sound samples that compare a GFS Lil Killer to a full sized Seymour Duncan Custom.

All sound samples were recorded through a Behringer V-Amp using factory presets straight into the soundcard.
--The Lil Killer is in a late 80's American Standard Strat.
--The Duncan Custom was in a 75 Les Paul Gold Top.

The Strat has a stock TBX control which was set at the midpoint. When you crank the tone knob past 5 the TBX control essentially removes the cap from the tone circuit and the tone gets a little brighter.

I was never totally happy with the bridge pickup in my Strat. I had been shopping around for a mini-humbucker solution and decided on a Hot Rails. I came across the GFS LiL Killer on Ebay and did a quick search on Google. It seemed like the folks at Harmony Central and the Fender Discussion Page had some good things to say about GFS.

Keep in mind that I am not one of those "golden eared, cork sniffing" pickup connoisseurs. I can tell the difference between a single coil or humbucker when I hear a song but that's about it. When I listen to the sound samples at Seymour Duncan I can hardly hear a difference between the various pickups. I hate the totally subjective terms that are tossed around to describe a pickup like warm, shimmer, quack, woody, smooth, transparent etc.

Personally I think the Lil Killer kicks some major ass, especially at $25 ! I even had to go back and record some of the sound samples again because I thought I forgot to switch guitars after listening to the completed samples.

At the GFS site they mention that you may have to slightly open up the cutout on the pickguard to fit the pickup.
Rather than modify an original pickguard I bought a pearl finish pickguard from GFS. I used 100 grit sandpaper to widen the opening just a bit. The area where the connection wire connects to the coil bulges out a bit. The higher you want the pickup the more you need to widen the opening. I don't think I removed more than a 1/32" near the center of the cutout. I don't think I would notice the small space if I went back to a stock pickup.

The pearl pickguard looks killer on the red strat !
