DOD YJM-308 Pedal Mod ???

[ianvomsaal]

I have a DOD YJM-308 . . .
I bought a RoHS compliant 3PDT True Bypass switch (blue Electro-Harmonix), and now I want to install this switch & add an LED.
I'm looking for the best sound, with no clicks or pops when I switch it on/off.
I have a few diagrams for wiring -- Which diagram is the best to follow, or is there a better one

What's the best resistor to use between the LED and DC Jack --  METAL FILM???
Which LED is better, 3mm or 5mm, and will the resistor's value need to be changed depending on what size LED I use???
And lastly, what's the BEST Resistor VALUE (I've read many different opinions): 2.2K, 1K ohm
Is there anything else special I need to do???
Thanks so much for all your help - Cheers . . .

Which diagram is the best to follow

I have always used the GGG just because it's what I have grown accustomed to.  There would be no difference between the two... eenie, meenie, mynie, mo.....

What's the best resistor to use between the LED and DC Jack --  METAL FILM???

Again, won't make a difference, whatever you have on hand - the metal film (assuming they are 1% tolerance) would be closer to the actual value stated.  Regular old carbon resistors are usually either 5% or 10% so might vary more than the value stated...  does that mean anything in this situation?  Not really... the resistor (current limiting resistor) is controlling how bright the LED will be.

Which LED is better, 3mm or 5mm, and will the resistor's value need to be changed depending on what size LED I use??? icon_question

The only difference between the two is size... larger LED would be more noticeable.  Current limiting resistor would be the same for either.  The value of that resistor would change depending on the color and type of LED - which of course brings us to...

And lastly, what's the BEST Resistor VALUE (I've read many different opinions): 2.2K, 1K ohm 

The value of the current limiting resistor will vary due to color and type of LED - is it a high brightness/intensity LED? - higher value, perhaps 8.2K... normal LED? -  4.7K....  I would suggest experimenting with just a battery, LED and a resistor tack-soldered on the positive (long) leg of the LED - then touch the pos.+ leg/resistor and the neg.- leg to the respective snaps on the battery.  I usually use 4K7 as a starting place and go either up or down depending on whether I need it to be brighter (lower value resistor that allows more current through) or less bright (higher value resistor that allows less current through). 

The only thing I would add is that the brighter the LED the more current is being used - batteries will die more quickly..
