Let me help you with a simple diagram. It will make everything sound great

Actually, I have just such plans. I have a bigger breadboard from some earlier projects and a 3.5mm TRS breadboard mounted jack. I found a 10k pot and a DPDT switch that also will mount on a breadboard. I can switch the signal from the collector of the transistor to the pot and send a reasonable voltage and impedance to my pedal and on to my recording interface. (I think
This thing just makes a square wave with no harmonics. (to speak of
) That smaller chip is just a dual 555.
But I'm just an old retired gearjammer. What do I know? It's worth a shot.
edit: I just checked and I get ~.95v between the collector and B+ with the speaker in place and ~2.3v with the speaker out of the circuit. The speaker is rated at 8 ohms. That is a much higher signal level than I am happy with, for input to any of my music equipment. An electric guitar will output something under 400mv (and likely less than half that
) with an impedance well above 10k.
