Quick comments:
JFETs are all over the place as regards drain current at a given gate-source voltage, even within a specific type number. When using discrete JFETs, you must either hand-select or design the circuit to be insensitive to these variations.
The biasing on the input source follower could be better.
The symbol for the JFET is wrong; it should be an N-channel JFET.
The panpot circuit won't work very well.
More detail (and suggestions for improvements) later if I have the free time...
