3PDT Bypass Wiring

[Seven64]

why is our FAQ different from GGG which is also different from madbean?

im really confused on how to wire one of these up without a PCB from smallbear

[StereoKills]

I always used the one from Tonepad

They are at the core, the same. Really the only differences I can see are the order in which the switches are arranged (meaningless really) and whether it grounds the effect input when bypassed (I've always done this, don't see any reason to stop).

[Seven64]

after some more searching, it seems lots of people have bad luck with the slow gear, so maybe they are working and its just the PCB that isnt

[Seven64]

which way do these switch?  when the holes are vertical, does it switch vertically or horizontally?

[Kearns892]

There are a lot of different ways of going about the same (or similar) things. IIRC, the one we show does not have the input grounded when bypassed while madbean's does. 

If by "vertically" you mean when the holes are aligned up and down then, yes the switch switches vertically (look at a single SPDT and it will make sense)

Try searching and lots of similar topics should come up.

Check this scheme out. I've been using it and works great!

I'm a fan of this one because it actually makes SENSE when looking at the switch.

There's a full explanation there though too...

Yes, because it's the only 3PDT wiring scheme that is fully symmetrical with all the inputs on one side and outputs on the other side and ground connections in the middle. Plus in addition, the PCB input gets grounded when switched to bypass mode eliminating any pop problem. Simply brilliant.

Yep.  This is the one I found when I first started building so I used it.  Then I stumbled across others and got really confused.

I like an earlier version of Darrin's Fig.b, that has the input on the inner tabs and the outputs on one of the sets of outer tabs.
