Switch pops (I've searched...)

[AceLuby]

Ok, I have a popping switch (I know, noob , but I can't find ANYTHING).

Here is the way my switch is wired:



So my effect should be grounded when not engaged and the caps should all be grounded out to prevent a surge.

Another problem (which is probably related) is that when I engage the effect it is really quiet and then 'warms up' to the volume it is supposed to be.  My guess is that I'm using an incorrect cap and it is taking longer to charge up (hence the slow volume rise) and longer to disperse the charge.  Is this where I should be looking?

Thanks!

  I ask about pulldown resistors and what is the brightness of the LED, and what circuit...not sure if it matters.

No pulldown resistors, but there is a volume pot at the end of the circuit.  LED is a 5mm yellow and is pretty bright.  Circuit is a one transistor booster circuit w/ a gain, volume, and tone control.

I wouldn't think I would need to add a pulldown resistor to either since when it is off it is grounded on both ends.

how/where is the gain pot wired? if it's up front (in front of the circuit) then you don't need a pulldown restistor on your input. so you could try disconecting the led to see if it's causing the pop. rylan

try a pulldown resistor just to see........

If that doesnt help it may be the initial surge of current to the LED, look over at AMZ ( I think ) there is a nice little article on there about LED's causing popping and involves using a cap aswell to limit the inrush of current to the LED to calm it. 

Thats the only 2 things I can imagine it being

Invariably, every time I got a bad pop, it was the led.   The amz led-cap is just all around good stuff.
