DIY Guitar Amp - Amazon Parts #guitar #miniamplifier #electronics

Here's how to make a mini guitar amp from Amazon parts.
Parts Used:
Parts in the video are in the above Amazon affiliate links.

The parts above are about $40-$44 depending on what speaker you buy. But as I mention in the video, you get 2 amps, so you can build a second one and that brings the price to *about* $20 each.

The mono TS mini plug is Tip="+", Sleeve="-"
A TRS mini plug is Tip=no connection, Ring="+", Sleeve="-"
Or
Save about $10 by removing the mini jack and soldering your 1/4" TRS plug cable directly to the board.

This amp uses a lm386 chip amp and a mini speaker. The bigger the speaker you use, the better the amp will sound(generally speaking). One important note, If you wire up another jack for the output, you can plug the mini amp into any guitar cabinet and play through that. It will drive any guitar cabinet up, including a 4x12 half stack! And yes, it will be pretty loud!

I've built these mini amps into many different types of enclosures- small cookie tins, cardbaord "chocolate" boxes, and even little folded printed paper boxes as shown in the video. The most important thing is to make sure your battery is securely fastened inside the box so it doesn't short out against anything.

You can also delete the battery all together and use a USB cable or an 9v wall wart adapter with the appropriate power jack.

Super cool build. Truthfully, this sort of stuff has always intimidated me, but I've always wanted to learn, and you made it really easy to follow along!

Very nice build. Would using a slightly larger speaker significantly change the sound?

I would like to add a 1/4" jack where the current jack is ( So I can position it where I want to inside the amp) so would I just remove the jack that comes on the circuit board? and solder the 1/4" jack into the circuit board? If so...which pins should I solder into? I believe there are 4 pins on the one that comes on the circuit board, just trying to figure out where to solder the 1/4" jack once the other one is removed, hope that makes sense, really interested in learning electronics, great videos by the way.

Another awesome video. Thanks for sharing.

Cool video - I’ve been wanting to build a mini amp powered by a usb battery pack. Any tips on making something like this running off 5v?

[ServingMyJesus]

That is great. Can you please say what I would need to build a bass version, please?

[loicflb]

To be sure, I have to buy a mono jack and cut one side to have a black and red wire to connect to the female jack 6.35mm ?

[giannim]

Would connecting the ring to battery negative to act as a switch mean that it wouldn't power on with when a trs cable is plugged in? Thanks for the cool video

[giannim]

I made one and im really happy with it thanks. If I want to increase the gain can I just short pins 1 and 8? The data sheet says that putting a 10uF capacitor between them gives a max gain of 200. Would you happen to know what just shorting them would do? Thanks again

[livecanal]

Wow! Just wow! The best video I have seen. Is it possible to short the Pam8403 board as well ?

[rossbuchman]

Did you short the gain pins on this one like your short video. I got it to work, but stopped working once I shorted those pins.

[meloman]

what are the requirements of the speaker because i want to try different speakers. The one you recommend is too expensive in my country

[peterdoylemusic]

I really enjoyed your video, I will have a go at making one

[randomuselessguy]

could i put any speaker in, and how could i do multiple speakers

[jeffgossett]

hi, I'd love to build this but not being familiar with the trs mono jack with shunt I found it hard to follow your video wiring. It appears you bridge two positives with a jumper wire but that is not in the diagram. A more explicit diagram would be much appreciated!🙂

Shove an OrangePi in there and run NeuralAmpModeler on it and you have a modeling amp.

We think of Pignose, I think it sounds good too; However, you had to have some basics in electronics, I don't think it's sold in kits like guitars.
