So I'm trying my hand at some mods to a toy keyboarding.
I am trying to create what I think is a low-pass filter. Kind of a wah sound if you will or really any kind of EQing that cold add to the sound. I'm not great with electronics and I'm using these types of little projects to learn.
I looked up basic RC and RL low-pass filters online and found a few simulators which I used to get an idea of what I wanted to do.
So...
I removed the speaker (i think it's a little 8ohm) and took those lines into the bread board. I have a pot (10k) between the leads of the speaker out lines. Branching off of that is a 0.1uF capacitor.
The reason I chose these values is because I have only 25ohm, 10kohm, and 50kohm pots. So, I plugged that into the calculator first. Then found the value of capacitor needed to start trimming out frequencies in the 1000hrtz range.
I understand that the frequencies that the human ear can hear(audio frequencies) are around 50-2000 (is that right?).
Anyway, I got it all breadboarded up and all I have to show for it is a volume pot...
Any ideas on how I could make this better? or work at all???

The part below intersects right after the "10k pot" and before the "audio out"
