Wizard Thumper output

[Muppet]

I've just swapped out a Quarter Pounder on a US Precision and dropped in an original Wizard Thumper. The sound itself is so much better but I was surprised about the output.

The Thumper measures 13.5k ohms and the QP it is replacing measures 11.5k ohms.

I was, therefore, expecting a slight increase in output. But when I compare the newly installed pickup with a QP installed in another US Precision I'm finding that the Thumper is slightly quieter.

What other factors might affect the output? The wiring is solid, string and pickup height exactly the same. I am comparing one bass with another here and I know I really should be comparing the pickup in the same bass ideally...

Any ideas on why this might be?

The only thing I can think of is the relative strength of the magnets. You could try a "pull" test to compare them by sandwiching a piece of ferrous metal between them and seeing which magnets "win" when you pull them apart. I'm blindly guessing here

Well, I worked out what's wrong. here's a clue!
