Maybe move a Send/Return block to the end of the signal chain and use the Send in "Branch Out" mode for Mono out, and then still use the Headphones for stereo.
Only thing is the Send out won't output EQ applied.

You can configure the send to act as sub out which would preserve your eq etc.
I have it set up so sub goes to my amp so that I can use the headphones. As soon as I have a use for the second return though I’ll probably just ditch it.

Probably although I haven’t tried. For me I prefer the sub out to my amp as I know the level is consistent and I can just tweak the overall volume on my head.
Right now I'm only using one of the loops for my Becos Mini Pro compressor. I don't have any other pedals on my board.
So it sounds like the GT1000 is going to process stuff in stereo in the signal chain as it sees fit, some models might not be and some others are and there is no way I can figure out to control any of that in the programming.
Ultimatley the Main out can be summed to mono by using only the Right output and don't try to use headphones at the same time in the left, leave Left unplugged. We can only hope that summing a bunch of stereo signal path to mono will not have phase problems. The SUBOUT, however does not have this summing option.
I thought of the following trick in the signal path to potentially convert the SUBOUT to two mono outputs, not entirely sure if this would work as expected, but please tell me if I'm on the right track to at at least make sure I can get MAIN and SUBOUTS in mono to FOH and to my amp..
So the idea would be use a divider in front of the SUBOUT, in dual mode. I would presume at that point that it will have split the signal into two stereo paths. Then in the mixer use the PAN/LR mode which I *THINK* should send all of the A path to the left side and all of the B path to the right side...essentially summing each of them. Does that make sense or am I missing something?
I would be interested to hear any other suggestions about how to deal with mono in this box...since for live playing, overwhelmingly FOH does not have two channels for bass and nor does my amp. I could have course use only the MAIN out and then a DI to go FOH/AMP...but then I'd lose the cool ability the GT1000 has to provide different levels and even different speaker cabs for MAIN/SUB outs...which is very handy...

@krfoss Great question which prompted me to look into this.
1. Connect monitors, speakers, or amp to Send 1 and/or Send 2, and connect headphones to L/PHONES
2. In Output Settings of Main/Sub Out, use the Main Output Select you want, ie LINE/PHONES, RECORDING, etc
3. In the Hardware Settings set Send 1 and 2 to SUB OUT AUX MUTE. Using SUB OUT will create a sound bleed into Main Out.
4. In the Sub Output and Main Out Setting use -10dBu
5. In Knob Settings, assign Knob 1 to SUB OUT. The main output knob on the unit controls L/PHONES.

Oh man, I can't wait to see if I can get this to work. Thanks!
If Send 1/2 are set to SUB OUT 1/2, Return 1/2 becomes Aux In 1/2, which will feed a signal through the MAIN OUT L/R. If the Send 1/2 are set to SUB OUT AUX MUTE 1/2, Return 1/2 is muted and will not feed the signal to MAIN OUT L/R.
I think the reason for an Aux In 1/2 is for the 4 cable method while using Sub Out 1/2 for FOH.
I’ve read on a couple of forums that you have to use a 1/4” dummy plug when Send 1/2 is set to SUB OUT or SUB OUT AUX MUTE. I’ve tried it and it doesn’t work.

Thanks for pointing out this potential problem !
I want to use output L and R as two mono outputs with only different EQ's (HPF/LPF/cab), one going to FOH and the other to an amplifier.
I am going to try and put a mono FX block (active but with effect-level at zero) just before the L and R output split.
I’ve not really experienced any phase issues so far. You can tweak and correct phase I believe on the fx loops, can’t remember where I read it but sure it’s pretty much a non issue for the internal effects.
Yea exactly. I want to send SUBOUT to FOH and main out to my AMP FXRETURN without a cab sim on it. Both mono. The GT1000 (non-core) has a new FX Expansion mode, which apparently adds an additional FX4 module as well as puts the whole signal chain into mono. I don't know why they didn't add that to the Core also with the recent firmware update. Let's hope in the future they might catch up the Core with that functionality.
Which FX will you use to do that?
So what I did was to use a spare div/mix pair, with nothing inside it. Put the div module in dual mode, and the the mix module in pan/LR mode. I think that is basically splitting the signal into two stereo lines, with the same signal on both lines. But in the mix module it brings back line A to the left and line B to the right...summing them from stereo to mono in order to do it. (knock on wood).
I'm putting it only in front of the SUBOUT in the signal chain so that main out will not be affected by it. I can get mono from the MAIN by using the right output jack. Its only the SUBOUT that doesn't have a mono sum built in. So this way I can listen in headphones at home in glorious stereo, or listen through the mains in either stereo or mono depending on the cabling...and trust the SUBOUT will always be mono. Hopefully. I'm not entirely sure yet that it works as intended.
I was thinking of using a distortion block or the chorus block (it has a mono mode) to sum stereo to mono. But I checked the parameter manual and it seems I do not use any effect block that produces stereo content. So now I am assuming that if I feed a mono signal the outputs L and R will be identical.
However I do not have a DAW to perform a 'nul-test' to check if I am right...

These are two screen shots of iZotope Imager Pro, which shows the stereo image (spread) of a recorded signal. The first screen shot is of a bass signal that I recorded which has no stereo effects, but it does have mono reverb and chorus. As you can see, the image meter shows that it is completely mono for the bass track. The second screen shot is a synth track which has a very wide stereo image.
Thank you ! That confirms my assumption, my use-case doesn't need 'fixing'.
But I have seen that the flanger and phaser effects are mono in stereo out (the effect creates stereo content). If you want to use these effects AND want have identical output on Output L and R (or Sub-Out L and R) you would need some workaround like Dewdman42 suggested I think.

Was getting confused about stereo vs mono output of the GTCore. But the Boss GT 1000 website clears it up. So any stereo effect that is selected using FX Expansion of the GT 1000, is converted to mono because DSP requirements.
"It's important to note that the additional processing required to drive an additional FX block means that the GT-1000 is automatically set to MONO output when FX EXPANSION is active."
