I installed it on a American Standard Stratocaster of the late '80s. The installation was amazingly easy, no welding needed, the overall operation lasted more or less 15 - 20 minutes. The sound is also amazing, being used to the buzzing and the somehow "low voice" and low sustain of the original american standard pickups, it will take time to get used to the new quality :) . The bridge humbucker is bright and crispy, the middle one is sounding like a solid and high quality single coil (maybe a bit under steroids) and the sound neck one is "fat", robust and colorful. In between positions are also round and pleasant. The overall quality of the product is incredible, it's assembled and welded as a skilled technician would assemble or weld it for his own usage, it's hard to believe it's a product coming out from a factory. It seems more like something put together by somebody with great skills and plenty of time.
