GES Doom troubles

[why-trv]

I'm building a stompbox using this schematic: http://www.geocities.com/diygescorp/gesdoom.gif
However, when I put it all together, there's no audible output.
I've figured out that putting the output resistor (between Out and Ground) makes the LM386 oscillate and 1M pot can be used to control the osc frequency. But it seems that the input signal doesn't affect the output at all.
Actually I'm a newbie at stompbox building, and most likely that I miss out some really simple point. I suppose that the schematic is somehow simplified by not mentioning some commonly used techniques.. Am I right? Maybe some input / output resistors? If so, what values should I use?
Still want to get this to work. Any suggestions will be highly appreciated.

I don't see a resistor between Out and Ground in the schematic.

Yes. There's none in the schematic. And when building just as it is in the schematic, there's no output sound.
I suppose there's something missing there. This thing is to know what it is.

How sure are you that you've built it exactly the same as the schematic?
Is this on a breadboard/perfboard/vero?
Have you confirmed that you get 9V at pin 6 and 0V at pin 4?
How "newbie" are you - are you 100% sure that you know the order of the pins on the chip?

No offence intended, but I'd say the majority of debugging that us DIY-ers do is related to construction problems rather than schematic errors.

99.9% sure. Built it using this layout: http://www.geocities.com/diygescorp/gesdoomlayout.gif
A perfboard.
Yes. I used a multimeter to measure that. I've got 0V at pin 4 and something like 8.8V at pin 6 (the battery has already got some use).
Well, yes, and I've looked through the datasheet before building.. And also, the layout seems to be OK, and I built using the layout.
