Low Impedance Pickup Research

[Mars Amp Repair]

[QUOTE=Helmholtz;n997765]Wow, that reverb is an unusual design.
How does it sound?
Trying to figure out where's the output transducer.
Could...

I want to share some recent low impedance pickup research with the foum members. The photo was taken on top of my research notebook where I placed all the...

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....

Dear Joseph!

Thank you for the input. Obviously this thread, started by you, is devoted mainly to pickups with single or couple thick copper...

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....

This is an important distinction. A change in overall volume is actually less noticeable than a change to some part of the mix I think. Otherwise we wouldn't...

I've never really thought about this until recently aside from the marketing aspects but I've been watching a lot of videos and reading a lot of articles/interviews...

Nice job in trying something new!

To quell the microphonic noise, put some packing foam in the current transformer hole where...

Hi, I have been busy building my new guitar to utilize the low Z pickups.


In the neck is the Aluminum single loop with ceramic...

It's true. I've been watching many videos of guitar players recently, but as a layman, I really can't tell the difference between different magnets. Recently,...

For those MEF members tinkering with Current Transformer (CT) pickups, the string loop wire type and gauge will affect the tone and output level of the pickup....

Nick,

Here are a few things to consider when selecting the right size, shape and coating for your magnet selection on your current 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....

I've wanted to try pickup building for some time, but have been put off due to having to wind thousands of winds of fragile wire. Even 500 turns would be...

Nick,

When tinkering with current transformer based pickup design keep these things in mind.
1. The input impedance and loading that the...

Necropost. I still have this amp and use it as my primary practice and recording amp.

Over time, I've tweaked some of the resistors to clean...

The stacked humbucker design used by almost everyone..

Anyone have an Idea how to approach this? The design seems fraught with electrical parasitic...

[Chuck H]

Thank you Helmholtz. The noisless pickup in that chapter would be the Lace Sensor. Which is quite different from the current stacked offerings. I did find...

[Antigua]

It's not complicated in terms of the number of factors involved, but the math which connects the factors together is complicated because it involves geometry,...

[Mick Bailey]

I forgot to include the code, which I've now attached.

The latency arises from the period of the lower note frequencies so yes, a faster processor...

Hi All,
If I look at the original schematic/layout diagram, it has a whole bunch of circuit points tied to the chassis, something like...
