Custom Pickup: P45/90/180 a P-90 with 3 taps

A customer had a guitar with a single P-90 and wanted some tone options with a single pickup... so while Horsing around in my shop I made this pickup. Some of the taps are close to one another in resistance but the tone is different becuase they start and end in differnet parts of the coil

It is a P-90 with 3 taps as follows:
0 to Tap1 = 5k
0 to Tap2 = 8.25k
0 to Tap3 = 12k
Tap1 to Tap2 = 4.2k
Tap1 to Tap3 = 6.25k
Tap2 to Tap3 = 7k
