Red Llama mystery

[yeeshkul]

I built Red Llama clone and have the following issue: the max. drive is much fuzzier/fartier and when i pick a note it ends up fast and breaks into octave-down sound of the same character.
I used my audio probe and i am having fuzzed signal in the input 100k/68n junction, which is obviously wrong .

Voltages are:
powered by 9.01V wallwart
5.45V at the pin 1
2.49V at pins 2-6
... the rest of the pins is skipped or grounded.

i tested another chip with the same results - and that chip works well in my other Llama build.
Any help or idea would be warmly appreciated

What chip are you using?  4049? 4069? Is it unbuffered?

I am using 4049, connected kind of gaussmarkov way - with unused inputs to the ground. The octave down would sound great if i was able to control it. The distorted signal in between the input cap and res is strange. My other Llama has got a clean signal at this spot. Maybe one of the feedback caps ...
I will post my PCB i guess, although the circuit is so simple that i probably didn't screw up.

I see i have the large capacitor grounded before the 1k limiting resistor instead of after. Can this cause oscilations or troubles of some sort?.

Is it a 4049UBE? UBE means unbuffered- buffered types won't work in this circuit.

That shouldn't make any difference

[yeeshkul]

Yes it is UBE. I can't believe this is happening. It is my 10th Llama build or so ... i have to start changing caps in the first place

In my experience this is how the CD4049 behaes when it is not getting enough juice. Try decreasing the resistor to V+.

Nelson, i clipped a 1k trim in parallel to the 1k res and managed to get a normal sound - so thanks a lot, you were right .
However the original sounds are fun so i put them in a separate thread.

oh yes!

Lurco, you were right. I just swapped the cap and the res and it is back to normal sound. Who would say that  . Thanks for pushing me that way.
Nelson was correct too - it also helped to decrease the resistor, but it sounded a bit differently.
