Make a Simple Electric Guitar Circuit

Want to try to make DIY Simple Electric Guitar Circuit from Hawaiian guitar?

Very good idea and cheap also which anybody can try.

What is Electric Guitar:

Electric guitar is guitar that take sound from strings like steel or nickel and change into electric signal using sensor.

Then signal goes to amplifier.

And this amplifier makes sound big and come out from speaker.

Circuit Working:

Parts List:

We need just one door bell electromagnet working on 230V AC and one transistor receiver or normal audio amplifier.

Place the electromagnet near guitar or banjo wires.

Be sure wires go same way like parallel with the poles but not touching.

Now electromagnet work like pick-up coil.

Turn ON amplifier and connect coils two ends to amplifier input.

Set volume nice and comfortable and then plays the guitar.

Now guitar sound come from amplifier speaker.

Try to move coil little bit here and there until sound come best.

When sound good fix coil tightly.

Use insulated wire for coil or else it can make unwanted noise.

Also put strong permanent magnet near electromagnet core and this will give more sound like high output.

Formula:

This formula show how strong the magnetic field (B) is in electromagnet or solenoid:

B = (1.257 * 10⁻⁶ * Ur * I * N) / L (f1)

Here what all these mean:

• B is magnetic field strength measured in tesla T.
• 1.257 * 10⁻⁶ is a constant (µ₀) which shows how empty space let magnetic field connect to electric current.
• Ur is thickness or type of core material.
• I is current going through coil in ampere.
• N is number of turns or spins in coil.
• L is length of the core in meters.

What this mean in actual life:

More current = stronger magnetic field.

More coil turns = stronger field.

Better core material (Ur) = stronger field.

Shorter core = stronger field.

So this formula help in many works when using electromagnets.

How to Build:

To Build a Simple Electric Guitar Circuit following are the building steps for connections:

Electromagnet Position:

• Put electromagnet near the wires of guitar or banjo.
• Be sure wires go same direction in parallel with electromagnet poles but not touching.

Making the Pick-Up Coil:

• Now electromagnet works like pick-up coil.
• Take coils two ends and connect to amplifiers input.

Connections:

• Use insulated wire to stop unwanted noise.
• Connect shielded wire from coil to input side of amplifier.

Set Up Amplifier:

• Turn amplifier ON.
• Adjust volume knob to get sound level we like.

Check and Adjust:

• Play the guitar and we can hear sound coming louder from speaker.
• Move coil a little bit and try different positions.
• Find spot where sound is best.

Fix in Place:

• When sound is good fix electromagnet tightly in that place.

Extra Improvement (Optional):

• Put one strong permanent magnet very close to electromagnet core.
• This gives more loudness and better output.

Final Test:

• Play instrument again and see if sound and tone is what we want.

Conclusion:

Be careful when touching electric parts.

Be sure electromagnet and amplifier are safe to use.

If not sure how to do ask someone who knows electronics.

To Make a Simple Electric Guitar Circuit are used in many music styles like pop, jazz, rock and blues.

Because guitar is flexible musicians can use pedals and amps to try different sounds and effects.
