ideal impedance ? sa pagkakaalam ko depende iyan.. may iba nagsasabi na around kilo ohms, ang iba naman ay nagsasabi na around hundred ohms sa madaling sabi iba iba kasi ang hilig ng tao sa larangan ng musika

pa OT po ano po iyong guitar pick ups ? string po ba yan ng gitara ?

sorry po newbie lang
salamat po sa magri replay

@Dizon nako hindi string yan.

ang guitar pick ups ay iyong guitar mic niya na naka built na mismo sa electric guitar
gaya nito

A pickup device acts as a transducer that captures mechanical vibrations, usually from suitably-equipped stringed instruments such as the electric guitar, electric bass guitar, Chapman Stick or electric violin, and converts them to an electrical signal which can then be amplified, recorded and broadcast.

tutorial tayo ng kunti
@Sir Piezo dagdagan ko na lang

In case you've ever wondered what is the role exactly of those guitar pickups or how they work, let me to explane it briefly. Every time you strike one of the guitar strings, you must have noticed that it vibrates. So the guitar pickups go to work and busily convert that vibration into a tiny electric current identical to that vibration. This electrical signal some times goes through pedal effects like overdrives and gets processed, altered, to finally arrive at the guitar amp, and from there travels to your neighbor's ears so he comes to knock at your door to express his disagreement about all this... (Unless your neighbor is Ritchie Blackmore) Anyway, there are generally two kinds of pickups:

MAGNETIC PICKUPS, consisting of magnets and coils, used as electric guitar pickups and
Piezoelectric pickups, consisting of piezoelectric crystals, used mainly in acoustic guitars and other acoustic instruments, for example violin. I'll explain you what this piezoelectric stuff is in a while, so don't let that strange word scare you.

So guitar pickups are magnetic pickups and how they work is that, as the metal string vibrates inside the magnetic field created by the magnet, it interacts with it and changes it. These tiny changes are picked up by the coil, which acts like an antenna, and then go through the jack, the cable, to the guitar amp and that's how you hear that beautiful guitar sound. So this device "captures" the motion of the guitar strings and no other sounds or noises from around, which is good. I think this basic diagram helps:

Now, as for the PIEZOELECTRIC PICKUPS. They are used mainly as acoustic guitar pickups and they just use a different system to translate sound vibrations into electric signals. "Piezo" is a Greek (what else?) word for "pressure" and piezoelectric means simply some crystals that, when any pressure is applied on them, they produce tiny amounts of electricity.

So these piezo pickups are mounted on the body (resonator) of the acoustic guitar and they vibrate. This vibration acts as tiny pressure on the piezoelectric sensor, which produces electrical signal identical to the vibrations. Then it goes again to the guitar amp. Smart, hm? Anyway, this is a simple diagram:

The history of guitar pickups goes back to the '30s. They were trying to find ways to amplify the sounds of musical instruments at that time. Today manufacturers like Seymour Duncan, Fender and Gibson create high-quality, advanced pickups, but the basic idea is the same.
