1W amp built from LM386 and spare parts. MASSIVE DOOM TONE

- Goal of this video was to see if I could build an amp with spare parts around the shop. Results were not as expected but still pretty cool nonetheless.
This amplifier was based off the Little Gem 2 by runoffgroove which you can find schematics here www.runoffgroove.com/littlegem...
I did not have all the parts necessary to build it as drawn so I had to improvise a little bit. The end result was a bridged LM386 preamp and power amplifier. While in the midst of the project I felt like a bridged power section really compromised your versatility as you would have to essentially double any tone controls or tone shaping circuitry.
A ridiculous amount of distortion was achieved by bridging pins 1 and 8 of each LM386 together with a 10uF capacitor and then connecting them to each other. A result was nasty thick distortion with out of tune harmonic overtones.
It would be very cool to experiment with some more with building small amps from these chips but the purpose of the video was to crank out an amp in an afternoon.
Enjoy!
Starting with a "simple" project that morphs into a more involved project. So, it's not just me
If you go back to it, the buffer actually uses a Jfet, you can setup multiple stages of that to allow for more control of the tone by inserting a tonestack. Check out the 1Wamp ... you’ll see what I mean.
Great stuff man!!
I wish you made pedals. Every other company I’ve contacted has been impossible to work with.
I found this video because I've got some lm386's laying around a couple 8" eminence, some NOS germanium transistor and some germanium diodes too.🤔
The LM386 is a demonic object from a parallel dimension. There are circuit tweaks yet to be made. What could be done with gyrators and hard clipping, I wonder…
I really like that you show the not so great moments in building electronic projects. Most channels show these easy 2 minute builds with no problems. Not ever realistic. I usually say the exact words you did at least twice every project. Also came to the same conclusion you did regarding just using one chip instead of two. The volume boost with 2 compared to one is very disappointing. The noise level was terrible with two, no problem with one. In my experimentation with the dual I did come across a circuit where it was insanely touch sensitive to your playing pressure. Touch the strings very lightly and 100 percent clean. More pressure both louder and distortion. Play hard and all out thick distortion. Or anywhere in between. However not practical for most playing.
Late to the party but hey that's a pretty darn cool little amp you built mr. Jim Morrison looking dude!

Peavy is king, lol.
I had to give this a thumbs up just for the Thin Lizzy bit! Kick ass! Nice work.
Les expérimentations avec le lm386 sont vraiment surprenantes, j'adore
I think I’m gonna try to build something similar. Thanks for the inspiration!
I love this! And thank you for not editing out the god damn its!
Wowza. Great work. Matt Pike will see this and special order one
That thing is a fucking beast. Like I'd buy that, at least in a different housing or with some shielding. One good thing coming out of this Quarintine are these videos for sure
Very nice dude!
With the gain up I hear badass Celtic Frost tones
How the fuck do you grab a handful of shit from your attic and a speaker from grandpa's radio and get a better sounding amp than the $500 POS I bought. Must be the literal blood, sweat, and burnt flesh that goes into it. Awesome video man!
