So, im a guitar player, and as you might know, electric guitars, use magnetic pickups to "capture" the frequencies of the strings.
There is a different kind of pickup, which is not actually a pickup, its called a sustainer, and basically, it takes the signal of the pickups and amplifies it to a coil that induces the strings into moving, therefore creating an infinite sustain and causing the sound to last for ages as long as it is on.
As an intermediate electronics apprentice, i want to do one myself, mostly because the originals cost around 200$...
What concerns me is that they say in the website of the original product that the driver has to be more than 2 inches away from the pickup, but the way i want to put it, it is closer than that. I assume that they say it has to be 2 inches away because the driver would mess up the sound coming from the pickup by changing its magnetic field.
I've been reading about faraday cages, i read that shoplifters often use tin foil to block the magnetic RFID sensors, that got me wondering, would i be able to "block" the magnetic field if i wrapped the driver in tin foil?
Also, would i have to connect the tin foil to ground to prevent humming?
Last but not least: Whats the best way to wrap a coil like this one: **broken link removed**
I need to wrap the pickup with a heavier gauge wire, otherwise the current flowing through it would damage the amplifier circuit of the sustainer. (this is because i will use a regular guitar pickup instead of wrapping a coil from scratch, for aesthetic reasons)
Thanks in Advance
