So a friend of mine just loves the Red Llama (me also), and asked me if it is possible to have separate gain control for low and hig frequencies.
He asked this after I suggested a eventual tone pot that could be added, like a BMP tone-stack for example...
So I just thought about it and since 4049UBE has about 3 inverters left, is it possible to:
1. split the input signal,
2. filter each half with a LP on one side and a HP on the other half,
3. send each filtered half to a gain stage respectively (x2 gains= x2 inverters)
4. mix their ouputs.
This is just a thought, I am a noob and really would need some help implementing those filtering...
What do you think?
