Low Power Combo from LM386 chip

Here she is then - purty huh? I decided that I needed a sacrificial combo amp for testing things that might do damage and like the whole world before me, came across the LM386, cheap cheap cheap and very old amplifier IC.

I promptly bought a batch from my local supplier and found an old announcement speaker on aukro.cz.
Then I got to work with the datasheet and some other bits that others have done eg: the ruby amp and the little gem.
The Ruby looked promising, having a jfet buffer made sense in a guitary sort of a way (I have one built into my stage guitar and it really immunizes the signal from the usual concert signal botherers) and I liked the idea of pushing the gain to get some fuzziness out of it.
I tried it and decided that I didn't need a buffer!

I didn't really need to vary the gain on the amp and would just use the guitar volume itself. I needed no volume pot because I don't play stuff through amps at home late at night and no one could describe this thing as loud, it's like 1/2 a watt or something.
When I tried guitar through the circuit without the jfet buffer, it sounded almost the same.
You see, I'm not using long leads into this thing and any highs that are lost from the impedance mismatch are the kind of highs that a guitar pickup either doesn't have or you really don't want coming out of a scratchy little combo.
In the end, I came up with this circuit:

You can download and use it if you like but if you damage anything or anyone it's your own fault and don't come crying to me!

I've made a little video so you can hear raw guitar through it if you want.
