What 3pdt wiring do you use; why?

I use the one from tonepad's offboard wiring pdf which allows for an led. I don't see a lot of people using this method, so i was wondering what are the other methods and what are their advantages? Here's a pic of the method I use:

I prefer to ground the input when the effect is in bypass which keeps the pedal from popping when I hit the switch. The only ground on the tonepad diagram is for the LED. I dont have a diagram though.

If you follow the connections for the switch in both positions, the above tonepad diagram does ground the input during bypass.  This is also why it states so at the bottom of the diagram.  I use the tonepad method above--no pops yet.

I use this one.  I think only because it was the first way I learned to do it and it made sense to my noob brain.  :icon_biggrin:

My Rat's LED diodes would flicker and alter tone when bypassed until I grounded the input.

Hey if you take a second look at that tonepad diagram you'll notice that the effect input is grounded via that jumper whe it's in bypass.  I use this wiring all of the time; it works well.

Well, after your initial posting, I had to prove to myself that tonepad wasn't lying by actually following the wires.  I figured you had noticed something I didn't, and I'd been left with a floating input on about 5 pedals.

what i understand from the above diagram is that when the circuit is bypassed, the LED connection is disconnected, the input gets grounded through the jumper and into the sleeve terminal of the jack. or i must be missing something.
i am what i am, so are you.

Yes, this is the conclusion I also came to when I followed the connections on the diagram above.  It states that it grounds the input in bypass, and it does.

I used the grounded input method because it stops high-gainers from oscillating and the bypass wires picking it up as interference.

Yo sam, that's the one I use. Well, slightly modified to remove the battery... changed the colors of the wires... but yeah, this wiring has been good to me.

Same here. It's just how I've done for years so I don't have to think about it like the other ways.

Compared em all...

Tonepad's is 'the one' in my opinion.  :icon_cool:

If you add a jumper wire from the orange input connection to the unused centre connection it will add the ground for the input bypass. other than that its the same as the tonepad version. (i keep the led in the middle poles also)

Please at least have 1 forum post before sending me a PM demanding something.

Is there any way to ground the input when effect is bypassed and to use a led with millenium bypass (useing a DPDT sw insted of 3PDT sw.). An answer willl be gladly appreciate, as i whant to put 2 effects in the same enclosure(like a TS808 and a Dynacomp Compressor).

Best regards,

Try ...reading... geofex.com. Specifically in this case, the Millenium C.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.
