Introduction: DIY Guitar AMP (LM386)

This is a small and powerful amp that can connect any guitar iPod

I made this this casing out of a Toyota motor oil can

    that schematic has a few extra parts than the 200 gain suggested on the datasheet (http://www.ti.com/lit/ds/symlink/lm386.pdf) may i ask what it adds?

    Your device seems to have a pilot lamp on it, and a power switch, that your schematic omits. You are also missing the 1K2 resistor on pin 1 for the standard 50 gain circuit too. Although looking at a group of schematics on the net I see lots of people seem to leave that part out. C2 should be a non-polar device.

    i didn't add the pilot light on schematics and i didn't use non-polar

    cap for C2 but it works fine thanks for telling me about the pin 1 problem appreciate your help my friend

    I was under the impression non-porous caps were better with high frequencies.

    I did not say it is a problem. As many schematics omit the part. The reference schematic has it though. I did not build the circuit with, and without it, in order to see what the difference was myself. Though I have built it with it, and I know it works OK then.

    You can see it here

    I happened to use an LM386 to boost the power output of something I was noodling around with in this instance.

    I like the concept here, but for many instructables users a schematic with a parts list will not be enough for them to reproduce this build. It is likely that if someone can reproduce a working amp from these schematics alone they are probably familiar enough with electronics that they have already built circuits like this. I think step by step photos would be helpful, as well as some photos of the construction process and go a long way towards increasing the quality of the instructable. Thanks for sharing this.
