(Note: this post has been updated to refer to the further developed newest version of the Pickup Wizard!!)

Here is something very useful and special:

GITEC member Helmut Keller (an expert in instrumentation for studio acoustics/electronics, and for RF,  and an avid guitar player) has put together an exciting tool for measuring our pickups:


Contrary to all those more or less useless (but unfortunately ubiquitous) DC-resistance measurements that cannot really tell much about the image a pickup will paint sonically, what we have here is a scientifically sound, highly relevant measurement of how the AC-impedance evolves over the auditory frequency range. The result is probably THE most important clue of how a pickup sounds.

What’s more, Helmut’s tool requires merely an ordinary computer with a reasonably good sound card (or audio interface) to run a few programs, and a VERY simple hardware measurement adapter that can be built (that term is almost an exaggeration!) by basically anyone – because it consists of nothing more than a few jacks/plugs, a bit of cable, and a single resistor, plus a switch.

Best of all, Helmut has given his software (as well as the accompanying article/manual/explanation he has written up: Pickup Wizard 1.0 to GITEC to post them here – completely free of charge!! You can download everything as a zip file Pickup-Wizard-Version-1.0.zip), unzip it and sink your teeth (figuratively, please!) into getting some really significant measurements done!

By the way: those impatient ones that do not want to dwell much on science but like to dive into applying it right away, they may skip „the theory“ in Chapters 2 – 5 of the article/manual/explanation and fast forward to Chapter 6: putting the measurement adapter together.

Helmut has tested the software at length with his WINDOWS machines, and at GITEC we have started to test it with LINUX operating systems, and on the Mac, as well. With LINUX, we are making much progress: it seems that there are no problems. We are still testing on Macs but are confident that success can be established on these machines too.

In any case, Helmut is happy to receive our feedback, and already plans to issue an updated „professionalized“ version of the 🧙🏽‍♂️ soon. I liked Helmut’s contribution too much, though, to keep it from you and simply HAD to post it already now/here!

‚Nuff said!!

Here is all the material: Pickup-Wizard-Version-1.0.zip

and here’s just the article/manual/explanation as a PDF-document for those who want to simply inform themselves first: Pickup Wizard 1.0 

Measure away, then, and have fun while really exploring your pickups!
