Pulldown resistor on FF build necessary before 50k pot at input?

[DJPsychic]

On my current FF build I have 50k pot at the input (right after input jack in circuit). Do i still need I a anti-pop pull down resistor in the circuit?

If so will having a pull down 1M before the 50k effect the tone of pedal? (assuming that's where the 1m goes)

[antonis]

If 50k pot is before input cap, it's already grounded..
(via pots body..)
Same stands for effects with Volume pot after output capacitor..

But, you can always wire 3PDT switch for IN+OUT grounded on by-pass.
(just for a peace of mind..)

[DJPsychic]

The pot is wired like the "bias" knob of the 69, it is not grounded to circuit.

[antonis]

In such a case, yes..
We don't deal with a pot grouded on lug1 (as usually) but a pot wired as variable resistor in series with input cap..

[DJPsychic]

Thanks for confirmation

Does the 1M effect tone?

[antonis]

If you mean tone with input cap, no..

But in theory, togheter with unknown capacitance of previous effect, yes..

[DJPsychic]

I meant if you removed 1M from
The pictured 69 circuit above, does it effect tone

[antonis]

Of course, not..
(it's set before input cap so it doesn't form any kind of tone filter..)

In such a case, yes..
We don't deal with a pot grounded on lug1 (as usually) but a pot wired as variable resistor in series with input cap..

which all shows on the relevant circuit diagram. which is not shown here.

And will never be..

Do you really need a pulldown resistor at the input? I have yet to experience any issues with popping with a fuzz face. but then again I wouldn't place any other effects in front of it.

[antonis]

I have yet to experience any issues with popping with a fuzz face.

Fuzz Faces don't pop by their own but their inputs caps might do it..

Any circuit with an input electro cap of 2.2μF is prone to popping either if it's a single transistor booster or an ornate multi-stage signal modulating effect..

[Electric Warrior]

I wire them just like a vintage Fuzz Face, with the input grounded in bypass. Maybe that's why it's not an issue for me?

[antonis]

Probably yes..
As with ANY other circuit wired with its IN & OUT grounded on bypass..
