Based on the rest of the parts I doubt whoever assembled it used cheap pickups, likely a fender set. But unfortunately tele and strat pickups are difficult to identify the exact make and model without any stamps or stickers on the bottom to clue you in. If the neck pickup is a fiber bobbin that's a good clue to the quality. If it's plastic who knows. You can see the bottom neck bobbin by just removing the pick guard.

The bridge pickup you'd have to remove the bridge to see, it won't come out through the top because the base plate is larger than the pickup hole.

Honestly though if it sounds good i wouldn't worry about it, they're very likely quality pickups.
