I only ran it through a Micro CUBE with a cheap headset, but from what I could tell, it had copious amounts of volume, but not a very nice tone (At least going from what we know and just adding different values to the mystery caps). I guess we need more pictures and better analysis and also I should be taking the breadboard down to the studio and feed it through a proper amp. But one thing's for sure and that's that I'll be doing a lot more with LM386 after this! Really cool device! I ended up with one op-amp on my board, 470n in and out of the chip and 47u across pins 1 and 8 and I can't wait to try it on a proper amp! 4 components for amazing distortion?!

captain_tango wrote:Tried it with LM386 N-1 and JRC386D now. Both sound quite a bit better. Less flatulent. Ditching the 10uF from pin 1 to 8 also seems to cool down on the craziness, but I still find that using just one chip with caps in and out sounds a whole lot nicer. Softer, surely, but better. So it wasn't for nothing. I think I will cook something nice out of the this chip, but I really look forward to seeing the correct cap values in the future if someone stumbles across them! Try using one JRC386D and go with 100nF from input jack to pin 3, tie pins 2 and 4 to ground and go 100nF from pin 5 to output and strap a monolithic 1uF across pins 1 and 8 and you have a fantastic little Keith Richards Style grind with only four components! Amazing

Also forgot to mention the pot is A100K, not linear as the PCB would have you think.
