Just installed a set of Phat Cats ( hb sized P90's ) in my Aqua Sparkle Tele Deluxe and a set of Quarter Pounders in my CP Jaguar yesterday. First, the Fender WRHB may be the worst pickups I have every used, so improving on them was not hard. Unless you are willing to have someone like Telenator bring them up to sonic goodness, you are going to have to replace them. I tried a couple sets of humbuckers I had laying around ( after purchasing the adapter rings from Terrapin Guitars ). Both sounded better, but not " the sound " I was after. So, my birthday comes around and I have a bit of cash on hand and decide to order a couple sets of pups. The Phat Cats are really, really nice. A perfect mix of chime and growl. If you play clean a lot, they bridge that gap that most humbuckers fall short on IMHO. Chime and note definition without sounding too muddy. One of my pet peeves is having to change my amp bass and treble setting when I change guitars with different pickups. Tele single coils, mini - hums and the Phat Cats all play nice on the same settings. Easy install, good wiring schematic. No problems. I actually liked the stock pups on the CP Jaguar, but since I have modded the crap out of the CP already, I decided to go one step further. The Quarter Pounds add a much more rounded sound, especially to the bridge position. Noticeably higher output compared to the stock Fender " higher output " Jaguar pickups. No issues with install. The fit right into the stock cover and claw. I modded the nearly worthless upper switch position with two 250k pots and a .022 cap to essentially mimic a Strat neck position. I highly recommend it if you don't mind permanently mucking up the control plate on top ( which I don't ). I have had many SD pickups over the five years I have been playing and have never had a " bad " sounding one. For price, tone and Not Made In A - Third - World Sweatshop quality, SD is rock solid. I ordered a set of the SP90-2's yesterday for my Tele Thinline P90 build. I can't wait to crank out some Social Distortion goodness with those bad boys. Here is the link to Terrapin Guitars for their WRHB adapter rings in any color you need. You can also get a full pickguard from them or Warmoth that will accept a normal sized humbucker. http://www.youtube.com /watch?v=Vz7UB956OqU Here is a video of the SD factory. As a small manufacturer, I actually find production process' interesting and a very telling sign of just how good the product is. Making one pickup that sounds good is cool. Making thousands that sound good day in and day out is very cool and much harder than it may appear.
