Adding the second pole won;t make a pop in and of itself. The second pole would be there only for the LED.

While that thread has been a huge reference in learning how to go about this - it seemed right to seek knowledge on the differences in goals.
If it really is a bother to have this posting here - I implore the moderator(s) to remove it with no dread from me.

I should be more thorough in the future I suppose.
I didn't mean to imply you were doing something 'bad'. I thought you might not be aware of it and quite a bit of it is in the same vein.

Its all good man. No worries.
Should I maybe 'bump' that posting up and move my question there, pending a request to the moderator to pull this one?

Seems like it might be better in the long run for others to learn some things ...

so I have a couple of old pots, and managed to Frankenstein the back plate of one to the turn plate of the other, resulting in a variable resistor that goes from 0(short)-50k (immediately after short) - full open.
Basically like a really slowly opening manual switch.
Im wondering if this might be a way of solving my problem.
The drawing might better depict what Ive got going...

above is how the pot. is wired
What kinda circuit would might work for powering up the led and mic with pot?
I suppose the high initial resistance would minimize the 'pop'.
A sort of analog voltage ramp?

after reviewing the thread mentioned pretty thoroughly
Power LED from 48 volt phantom power
(to the point where I am starting to learn some of its content)
I have come to terms with the having to be a slight 'pop'.

Also tossed aside the the variable switch as well. Way to far off target.

I will take some photos this week and get a photo.
Just for sake.
Nothing special of course - just some parts recycling.

I have not followed this thread (tread?), but... what is a "variable switch"? E

variable switch was a bad way of saying variable resistor/potentiometer with a built in power switch.

Ended up going simple instead, DPDT.
This was the quietest 'thud' with the limited components on hand.
works with or without phantom. good.
My friend is happy.
Thanks for all who shared their experience and previous topics.
