Do I have to take the pup out to measure resistance with multimeter? I want to check my JB - it seems to have low out put to my ears. I'm just a lazy bastard and don't feel like unsoldering the pup unless I have to....
you can measure by plugging in your guitar cord, place the ground lead of your meter to the shaft, the hot lead to the tip.
your measurement will be slightly lower, but certainly close enough to determine if your pickup's output is low
mY JB is measuring at 16.30. I think that's a normal range from what I have read. The issue is high E string always sounds dull, so I just raised the pole piece a few turns higher to get an even string balance.
The pickup is F-spaced so the High is off center just a bitat the pole piece. That's probably what's causing it. An extra screw turn or two seemed to do the trick.
