Simple Mute

[Buffalo Tom]

Building a simple MUTE switch to mute the guitar signal after the pedalboard and before the amp. Maybe I'm overthinking this but how do I mute a guitar signal the "best" way? Thinking of three different ways to do it.

POP^POP _POP
No1 seems to be closer to non-popping..

Hi
The output impedance of the last element  of a pedalboard can be low (e.g. a buffer), so I would not ground the input.
I'd prefer solution No3 as it looks  the more logical to me.
The other two will almost always work fine though

I think the red pop is winning.

[edit :] further observation suggests my red pop is winning. [&] mine would be duckpops.

You want to ground the amplifier input. Otherwise any buzz picked up on that perhaps long cord will come through.

I would not ground the pedalboard output. Many boxes won't mind, but a few loosely-contrived circuits could bust a gut trying to drive a short. Anyway, why do it? (This is not like wires in a tight box, where unselected wild signals fly through the air to corrupt a selected signal.)

Thanks for your reply. But how about version 3 where I don't ground the pedalboard output. Im grounding the output on the mute box. And that is the closest to the amplifier input I can get.

My monitor is not that wide. Now I see it.

What i would do is place 100k (or something along those lines) resistor between input and output (input - 100k - output), and ground only the output in order to mute. To unmute, disconnect ground and place a jumper across 100k resistor. That way you wouldn't have to worry about grounding something that may not like to be grounded. Or you could go crazy and make an active solution, for example using phototransistor or an ldr (input - phtr/ldr - output), and vary resistance using led.

Thanks!  Something like this?

This is a job for the Burst Box.

Exactly! Although, actually you might be just fine with "3" (output to ground). I would try several combinations to see which one has less (no) pops, clicks etc.
