Hi guyz..

My best friend gonna start playing bass guitar and he has a very low budget.
I thought how will I be able to help him so I got to think about to build a DI box so he could connect it to a stereo or something..
I got this schematic for the tech21 sansamp bass di driver but i have 1 unclear thing:
In the center of the page u can see "bypass" and it says - "two jfet switches (j112) controlled by flip-flip".

How do I gonna connect 2 jfet's that way??? Or this schematic isn't propered??..

Ty for answers!!
