Build a Guitar Amplifier Easily

So here we have another project that is all about to build a "Guitar Amplifier" which is a portable amp and works with all types of guitar without a pre-amp.
As we know that the OP-Amp amplify the signals such as LM386 so this is able to work as preamp and amp.
So if we add a circuit of lm386 preamp and lm386amp it will become a fantastic guitar amp. Here is a schematic i designed.

This is hard to design but it works 100% perfect with all types of guitar. And all the parts i have used in its design are easily available in the market.

Components Required:
  • 2 - IC LM386
  • 2 - Capacitors 10uf
  • 1 - Capacitor 100uf
  • 2 - Capacitors 0.0047uf [Code 473J or 473K]
  • 1 - Resistors 100 Ohm
  • 1 - Resistor    10  Ohm
  • 1 - Potentiometer 10K Ohm 
  • 1 - LED

It will work with small and large speaker but it is not suitable for too much small speakers.

Q: Do we have a video tutorial and demo about it..???
A: Yes , We do have a tutorial and demo about it at our YouTube channel and link to its video is written below.:
How i built it...??? 
I used a wooden box and did few things to it which are clearly shown in the images below:

And after all the thing done i just packed it and tried to color it with black,yellow and red colors. I tried to write something but i am not good in drawing or designing the outside and that's why an airplane i built was crashed (because of the dry paint drop was stuck in the elevator)....LOL...!!
And here are the pictures when i finished it.
So if you like to create a guitar amp then you don't need to wait more download the circuit and start creating it. I believe you're gonna love this project. And also share your questions and feedback with me.
[Next project will be about a OverDrive Guitar Pedal]

  1. I am glad for writing to make you understand what a wonderful experience our daughter found studying your web site. She came to find many details, which included what it's like to have an ideal coaching character to have many others very easily learn about various impossible matters. You actually surpassed our own desires. Many thanks for offering these beneficial, trustworthy, educational and as well as easy tips about that topic to guitar amplifier!she rebuild this new guitar amp ,i am so happy she can do that!

  2. What is the value of the capacitor in series with the speaker please?

    1. That should be 220-470uF but in order to have more bassy response use larger value capacitor like a 2200uF voltage ratings of a capacitor be at least 16-25v
