I've been thinking about this lately...
When the Super Distortion was first invented, there was no such thing as a high-gain amp, and there wasn't the wide range of overdrive pedals that there are now. So people needed a pickup to push their amp into overdrive, especially at lower volumes.
The trade-off, many people found, was that high-output pickups don't have as much tone as low-powered ones, right?
But these days, pretty much every amp on the market has a shiteload of gain in it. And if that's not enough, there are a million great pedals available. So why bother with a high-output humbucker? If you want to push the amp harder, you could just use a low-powered pickup, and then use a clean boost pedal. That way you get all the level you need to push the amp, but when you want to back off you have all the tone and dynamics of a more subtle pickup.
Obviously a lot of players are still using monster pickups, so there's a hole in my logic. What am I missing?
