What guitar were the pickups in?
I have had 3 guitars with APC pickups. I'm not sure what models they are but they are not all that hot, much more of a PAFish kinda of output. I had a Gibson SG and the stock pickups were a little hotter than the APCs. However, when it comes to tone the APCs are about the best humbucking pickups I've used. They also sound great when they are split.
If directed to me, mine's in an Agile 3000M.
You shoulda popped out the pickups and see which one's you had . I do know that not all of their pups are high output. They are real gems though. I have to say, since I can't find Ultrasonic pups, these will do.
It's awesome to see that you were happy with the sound of your pups while being split. I'm curious about one of their pups that's supposed to produce a nice "acousticy" tone when split (I think the Melvin).
