No input capacitor?

Hi, I'm still kind of a noob when it comes to pedals, but I've gotten to the point where being in my possession isn't a death sentance for a pcb. I want to order some stuff off tayda and I'm thinking of making this stratoblaster pcb, but looking at the schematic there doesnt seem to be an input capacitor. How does this work? I don't think the resistor does the dc blocking thing, does it?

(scroll down for the schematic)

That kind of JFET stage is one pretty common exception to the input/dc blocking cap rule. The other is some tube amps that lack them, a similar situation with input referenced to ground instead of a bias voltage.

So the schematic is OK.

It is possible to rig tubes or JFETs so that the input grid/gate "naturally" wants to be at common ground potential. This is one.

Welcome..

IN any case, you could easily cram a 10nF cap between 3PDT switch and PCB IN..)

IMHO, you shouldn't have popping issues both due to IN grounded when bypassed and cap low value..

Ah right fair, I might try an sho instead just because I found a cheaper pcb. Thanks though
