LM386-based “Esteli” demo by Alex Wilson

an older video, but one i’ve been wanting to post for some time. this is Alex Wilson of Son Cats playing on one of the several cigar-box amps i’ve constructed. this one, in particular, had one of the best sounds during the more work-with-what-is-available days. i thought the video was a great demo of an application best suited for a small 1/2 watt amp. thanks, Alex.

The Esteli: an LM386N-based cigar box amp

The Esteli: Cigar Box instrument LM386N-based Amp from abram on Vimeo.

Here’s the latest in general purpose amplifiers made from reused parts. The enclosure is an old cigar box for which i have quite an affection as an enclosure. I really do love the sound of wood in both the recording process and amplifiers. In the video, you can really get an idea of how it treats the sound when i open the top.

As opposed to the LightBox, the Esteli has two knobs. The top is for volume and the bottom a 10k pot in the gain look between pins 1 and 8 on the IC. I’d probably recommend a 50k in this configuration, but it does make the amp really loud which i think is better for the instrument side of things. The gain of the amp then floats around 100-200 depending on where the gain is set. For more information, see the LM386 Datasheet.
