How to Make a Guitar Amp (Cheap)!!!





Introduction: How to Make a Guitar Amp (Cheap)!!!

This cost me around 7 bucks to make this including all the materials for the box

This is very easy to make it only took me about 3 hours to put everything together.
It give a nice clear sound and also has a distortion fuzz knob for electric guitars
i used this schematic from Flickr user cairn_idris who has made a much
more readable circuit drawing and posted it here.If you follow this exactly then you
should have no problems.Its best to test it out on a Bread board before you start

Step 1:

I bought all these parts at my local radio shack.
You can also buy them online though.This list
Was created by Aidan Collins and edited by Me.

IC chip, LM386N

220µf electrolytic capacitor

100µf electrolytic capacitor

0.047µf ceramic capacitor

0.01µf ceramic capacitor

10Ω resistor

5kΩ Audio-taper Potentiometer

25Ω Rheostat variable resistor

8Ω speaker

toggle switch

¼” mono phone jack


circuit board

hookup wire

9-volt battery or supply

Step 2: Tools

You will also need these tools





Soldering Iron

Step 3: Assembling

First you should test it out on a bread board.
After that if it all works you can move on to the
circuit board.I am using a parallel circuit board
but you can use a single cell board.Start by putting
on all the pieces and then begin soldering the pieces
to the board before moving on the the pots and speaker

Step 4: Putting on the Pots and Speaker

Next after soldering the components to the board you can
start adding the pots.Its best to stat with the 5k pot because
its easier to put on first.Next we can add the Variable resistance
and the speaker.Make sure you wire everything correctly according
to the schematic and test it out!

Step 5: The Box

I made a quick box out of cement board and wood
and hit it with a quick(and lazy ;) coat of black spray

Step 6: Done!!

Almost done.Just hook up everything according to you box
that you made (if you made one) and done!

    Nice Work!!!!!!... Metal head here.. could you please post a diagram showing the components that u have used here.I'm not able to find out from the second diagram which capacitor you have used where.

    Sorry for the late reply. All i used was a electric capacitor instead of a ceramic one because i didn't have one at the time. It still worked perfectly. Cheers!

    plz post a video on youtube and i beg u plz send me a proper circuit diagram schematic of the same to
    because in your prototype image u have not mentioned the places of ceramic capacitor


    Ravage32 (author) pmadithya do make me a same one.....actually now this days i m suffering from money, plz suggest me to build an amp around best as e-mail help not for me only for rock \m/-\m/

    can you post a video please? (I really need to know how loud this amp is!!!) :-)

    one question...
    did u or did u not changed (switched) 5k pot and rheostat cause in the 4th part i think u did it.

    Nice work. Made one meself and instead of building a cabinet, used a 5 L beer can. Works great.
