Hi! I'm fairly new to installing pickups, so I need some help on my latest installation attempt.

I installed a humbucker set in an Agile Valkyrie Natural Ash the other day. The bridge pup turned out fine, with great output and improved tone, but the neck pup's output was very weak.

I don't think I soldered the components improperly, so what could cause this problem (besides a defective pup)?

I'd appreciate any help and advice. Thanks!!
