Pro Channel Modules on Tracks or Bus?

From what I've gathered, many folks put the Pro Channel Console Emulator on EVERY individual track. My question is........If I'm outputting (not "sending") all my guitar tracks to a "Guitars" bus with the Type A console PC module, do I need to have the module on each individual guitar track also? Seems redundant if all the signals are being routed through the bus with the console on it. But I have seen some screenshots that have it on the tracks and the bus.
 
Just trying to save some CPU and time.
 
Thanks for any advice.

Well, you can use as much or as little as you like. As I understand it, all the console emulator modules do is kind of replicate the non-linear response of the consoles in question. Effectively, they're faking the electronic behaviour of each channel and bus in the real desks.
 
So to make it as much like the real desk as possible - if that's your goal, then yes, you'd have it on every channel and bus, with the tolerance buttons all on (to emulate real world manufacturing variances between channels). And you'd constrain your number of buses to something that relates to analogue console reality; four or eight, or whatever.
 
Of course, "authenticity" is not always desirable. And it's always worth remembering that console emulation is - at least partly - reproducing things that console designers go to very great efforts to minimise.
 
For myself, I happily use far, far more buses in the digital domain than I think any analogue console has ever offered. Sometimes in the 20-30 range, if it's useful for the mix. And a lot of the time, these are tricksy chains of channels feeding buses, feeding more buses, with sends going all over the place. I wouldn't want to have a layer of Console Emu tomfoolery at every step in that.
 
I tend to have it on every channel, and only on what I think of as "end point" buses. So that'd be the master bus, my general reverb bus, my general delay bus, and my drum parallel bus. 30 buses worth of console emu can start to get audibly weird, especially when you've got a bus feeding another bus.
 
Another exception case is when I do drum overheads as Mid-Side, which I like to do sometimes. In that case, I'll have the mid channel with no console emu, going to an "all overheads" bus with console emu. And I'll have the sides channels going to an "overheads sides" bus without console emu, that then feeds the "all overheads" bus. So I've only got one layer of console emu on my overheads, despite the complex routing.
