Muppet Posted February 15, 2017 Share Posted February 15, 2017 So, my Wizard Thumper has a DC resistance of 14k, My SD Quarter Pounder has a DC resistance of 11.5k. Both are fitted in to American P basses - same strings, same setups. The QP is noticeably louder than the Thumper (although both are louder than the Custom Shop 62s fitted in a third Precision). In my simple world, I would have thought the Thumper to have the hotter output. What other factors (if any) would determine pickup output? cheers Quote Link to comment Share on other sites More sharing options...

I'd also add that resistance is also dependant on the number of turns in the coil AND the gauge of the wire used. So without knowing all this resistance if the coil doesn't really tell you a lot. The truth is a pickup works through induction, not resistance. Quote Link to comment Share on other sites More sharing options...
Muppet Posted February 16, 2017 Author Share Posted February 16, 2017 Ah thanks both, makes sense. Just wanted to be sure I wasn't writing off my Thumpers, as from a sound point of view they are excellent. Quote Link to comment Share on other sites More sharing options...

The resistance is somewhat indicative of the inductance but depends on wire gauge (and material though it's going to be copper). Resistance is more readily measured which means its often quoted. To add to things the inductance itself varies with frequency depending on the construction an materials (magnets / core) used in the pickup...
