Just oppened my box of CS 54" pups and I can't tell which pickup is bridge, middle and neck? Two of them have letters "CS" written on the backside in white crayon. The 3rd has no markings on it. Specs on the box call out: Bridge: DC Resistance 6.5k / Inductances 2.75 henries Middle: DC Resistance 5.9k / Inductances 2.4 henries Neck: DC Resistance 5.9k / Inductances 2.4 henries How do I know which is which? I'm jones'n here" Eeeek!
