Hemholtz is correct about the audio impedance rating of Shure transformers. However,
I want to add how the guitar pickup sound is governed by the following....

Krzysztof,
When you reduce the AWG wire size by 3 sizes, you reduce the resistance by one half assuming you are using the same length of wire....Last edited by bbsailor; 03-19-2024, 06:48 PM.

Nice job in trying something new!
To quell the microphonic noise, put some packing foam in the current transformer hole where...

Hello members,
What is your opinion about the effect of using two magnets per string like what is used on bass guitar pickups?
My...

I have a simple expeiment for you to try to obtain independent outputs from each string.
1. Obtain an audio transformer...

Nick,
To effectively design a guitar pickup you need to know the input impedance of the device that you are plugging it into. Here is an example....

OK but grounding the strings does reduce the noise. The Platemate is good way to add a ground connection by just soldering a wire to it and connecting this...

Here are some design tips to consider with toroid CT.
1. Find a round solid wire that snugly fits the toroid opening. If it is slightly loose...

Antonio,
Getting a more acoustic sound is a balancing act with this current transformer (CT) type of pickup.
1. The string loop...Last edited by bbsailor; 04-20-2023, 02:20 PM.

Nice work!
Try to obtain an LCR meter to measure the output from the current transformer. The lower the output impedance means...
