Pearl Octaver and Boss OC-2 jfet input stage

Both the Boss OC-2 and Pearl Octaver (Low Rider) have identical single Jfet input stages followed by an opamp gain stage.

The question is, are these single jfet inputs even necessary or are they a leftover from the original bypassing mechanism? It seems like the pedal should work exactly the same if the jfet stage was left out, or am I wrong?

Input buffers. They are usually skipped when building "replicas".

Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

Right, that is what I thought but the Low Rider keeps this input stage.
