Sensor for guitar pickups

I will need a similar pickup. I am planning to wire a custom one. There's many luthiers out there that wire good enough.

Hi,

Could you explain your requirement a little more? You mention "it suppose to measure the dynamic magnetism from when the strings vibrate in the magnetic field",

but I didn't understand it. Do you wish to measure some electrical/physical value in particular or generate a signal to play (a normal guitar pickup already generates such a signal),

or to make some improvement in some particular area (which area)?.

You also said you want to hide a sensor inside a guitar pickup, but where? Are you intending to remove part (if so, which part) or all of the existing pickup to make space?

It was all unclear unfortunately : - (

@Alper: Your requirement does not sound similar to what Ed is asking for. Since you mention wiring a pickup, it sounds like you're trying to build a custom pickup using

conventional methods. Ed's post appears to imply that he wants something additional to a conventional pickup, or to replace or enhance some aspect of a conventional pickup

(his exact requirement is currently unclear and requires more input).

you could potentially use a hall effect sensor if there is already a magnetic field, the strings will have some parasitic magnetism that should be picked up even if separated by some reasonable distance.

I'm a pickupmaker. But now I'd like to dig in deeper into the magnetism that happens inside a pickup. I'd like to monitor what happens with different design in magnetism, and I need to measure it.

So, because I'm a pickupmaker, I design a pickup where I hide the sensors inside the bobbin, put the wire where it suppose to go, and measure what happens to top and bottom of the coil and on the different sides, and what happens when I change the magnetic field. Of course I'm thinking of just using magnet and hall-effect sensor as the only pickups, So I have lots of magnets for such experiments.

By the way, I found what I was looking for.  http://no.farnell.com/allegro-microsystems/a1324llhlx-t/sensor-hall-effect-linear-nw/dp/2250904?Ntt=225+0904 

That sounds quite advanced. I'm worried you may be in the 'noise' without some sophisticated sensor, after all you're in a magnetic field (I don't know how strong, I don't know much about guitar pickups) yet only want to monitor the change, and you're presumably not cutting much flux with the plucking of the guitar. I take it you want to measure the changing field and not the static field, since static field may only very slightly help you determine what to adjust for the best sound.

Even dynamic field may only help partially, since I suppose best sound is not the same as location for strongest measurement since that is just one parameter. But it may in some manner aid you to adjust your coil parameters.

It's worth a try since hall sensors are fairly low cost. Maybe try several different sensitivity ones to try out. A very narrow diameter coil as a 'probe' could also be an alternative, but I'm guessing this is not practical to construct even with the thinnest wire (I could

be wrong) and may not be useful anyway if you are in the noise.

Another thing is that even a difference of a fraction of a millimeter may affect the measurement from one location to another (I'm guessing, not knowledgeable on this unfortunately).

There are more exotic sensors, but it would be good to get an idea of the level you're currently experiencing, so a measurement with a hall sensor may help. I'm wondering if it may be easier just to have dozens (maybe a hundred?) of different pickup coils made, each with a slight variation in parameters like diameter, and then record the audio results rather than actually try to measure the field, to try to find a trend between desired sound and coil parameters.

Anyway, that is just some random thoughts.

Do update the forum on how it works out. This is very interesting. I'll also try to think of other ways to achieve what you want.
