It was to improve a Squier Affinity. The diagram is clear and soldering went easily, the mounting screws fit the standard bridge without any problem. The wires are long enough to reach the pots and selector even if the plate is inverted, as mine is. The tone is both more powerful and much quieter but especially better in beauty, warmer with more of everything, harmonics, punch, transparency, the whole squad.
Compared to Fender Noiseless pickups this one kept a tiny little bit of hum, but maybe because the Fender set is delivered with high quality pots, resistor and capacitors. The residual hum is not annoying at all, just an piece of info I add because the techies out there want to know every detail.
My Affinity has those little cheap pots, I'll probably replace them next time I change the strings, quality pots cost only a few euros more than low-end pots so it's worth doing and they will surely be more durable.
Totally fine pickup and recommended for any use, it's hot enough for metal with high gain distortions.
