Is it possible to use a Boss FS-5U Pedal in the footswitch input as a boost input for my acoustic guitar for solo sections? I’d like to create a channel with extra gain and effects and acccess it only when needed.
It would save me bringing a separate DI/Boost pedal to gigs.
Appreciate it!

Your plan doesn’t seem as easy to implement as one might initially think.
Perhaps the following would be worth a try:
You would need to split your guitar into two inputs, e.g., 1 and 2.
1 would be normal, and 2 would be the more aggressive one.
Send both channels to an AMM and adjust them there if necessary so that channel 2 becomes a bit more “important.”
Configure your footswitch to mute it channel 2.
If you mute channel 2, you will only hear the normal channel 1.
And if you unmute channel 2, it would override channel 1 while playing, and you would hear channel 2.
Very creative SQ user.
My solution to also consider:
-same as SQ user for the split but no AMM involved, just Mute/Unmute the extra channel will add more gain when played together, even if they have exactly the same setup.
But you can tweek the extra channel as you need to push it more.
Thank you both.
Frenchie, I’m going to give that a shot and report back. That’s pretty much exactly what I wanted, but I didn’t know I could have two channels for one input. Pretty cool idea.
SQ User, very creative solution. I don’t have any experience with the AMM feature yet, but I’ll look into that as well.
I stress out the point that you’ll need an XLR splitter to achieve that.
Correct, but as long as he doesn’t have a CQ-20B and uses a Hi-Z In for his acoustic guitar. )
But in any case, if necessary, the signal could also be “split” from one channel to a second using an aux (although only possible after the PEQ).
This would only require one additional cable - and, of course, a free aux.
With a guitar, this wouldn’t normally pose a latency problem, except in the case of directly adding the two channels without the AMM.
I keep hoping that one day an update will deliver flexible input routing (even if I doubt…).
I think so too, since they will probably also in the future want to keep the structure as simple and clear as possible.
So your advice was necessary, that he doesn’t think that it would be possible to split inputs internally.
Can you say more about how to achieve this?
Does this sound accurate? Any issues you foresee with this routing?
In principle, yes.
Unfortunately, also yes.
The external analog detour introduces additional latency, so the phase is no longer correct if you simply mix this channel directly to the original.
In that case, the idea would still be to use the AMM to attenuate the original channel.
Maybe you’re the first to try it. 
And the question is: How are you currently connecting your guitar to the mixer - directly or via a DI box?
If the latter, which one?
You guys are legends. It works gangbusters.
At least in the PA I have set up in my space, I’m not noticing any latency or phase issues.
I am running the guitar direct via 1/4”, sending it to Aux 1 and using a 1/4” jumper cable to run it back into the next open channel. Copied and pasted all settings from my original channel, and then bumped the gain and effects slightly on the boost channel.
For the footswitch, I had a pretty elegant solution going where I used a Boss FS-6 to mute/unmute each of the channels, but muting the original doesn’t seem to be necessary right now. Might get a FS-5L unless you guys know a latching pedal that doesn’t require 9V so I could leave it plugged in. 
That’s strange, because I think it’s logical that there MUST be a phase problem when simply adding (mixing) both channels together - try feeding in some noise.
But if you don’t hear it, that’s also fine, of course, and I’m happy for you. )
The FS-5L you mentioned requires 2x AAA batteries, but probably only for the useful LED when the pedal is “on”, right?
That way, the batteries would last “forever”, but i think it would also work without them.
