Thats funny, as I read this there is a ruler sitting beside my computer

so I would be kind of a jerk if I didn't get up and walk 10 feet.
The pickups on my L2K measure 3 3/4" by 1 11/16" (kinda random) or 94mm by 42mm. String spacing is pretty standard 19mm at the bridge.
Sorry, don't have a 2500.
