Help extracting an Ibanez electronic switch from a TS 808 schematic...

Question:  While the JFETs used for switching in Boss, DOD, and similar pedals have a low "on" resistance, it is rarely zero ohms, but something low enough to be considered like a "low resistance wire".  I'm wondering if, assuming there are no suitable JFETs for switching with near-zero on resistances, it would offer any advantage to use a pair of JFETs in parallel such that the "on" resistance becomes their combined parallel resistance?

Now that I think of it, though, I guess that means their "off" resistance would still be parallel too, which is not such a good thing since we want off to be a higher, not lower resistance.

Boy, that was a dumb idea.  Sure glad I didn't think it.

Now I'm just wondering, but was that post meant to be a lesson for all of us, or do you just type as you think? It really seemed like I was flying along with the synapses of a genius, or a mad-man. Not quite sure.

I was typing as I thought.  Initially, I was intrigued about the idea, but as you can see, when it dawned on me there there was the "off" state to contend with, and I had been too preoccupied with the "on" state, things kind of ground to a halt.

At first, I thought that would be justification to simply drop the post, but then it occurred to me that such less-brilliant-than-you-thought-it-was "insights" happen all the time, and newbies need to know about them.  Both to encourage them to follow their flashes a little bit further along and consider the bigger picture, where things might have unforeseen consequences, and to remind them that folks who they think know a lot ALSO have such thoughts that end up being dead ends.  Hell, dead ends are probably more the norm than the exception.

Mark, I think it´s cool to express your ideas, so we people with less experience can learn...
Now, since this thread seems to have slowed down a bit  , news report:
I´m trying to design a PCB for the boss switch, and man, WHAT A PAIN IN THE *SS THAT IS!! I´m running out of pencils and brain cells! Yeah, i know there are softwares for that, but I don´t want to learn yet another soft just for one simple circuit.
Is there not someone that has already made it??
I´m stubborn, I´ll keep trying...
