Actually I have another reason for putting everything in path A and using guitar/variax input settings.
The reason is that this way I only need to change the volume setting on one channel in the mixer when I need to tweak the volume. I don't like using the amp volume because sometimes when I want to lower the volume on a patch the knob on the POD is near max. If you then turn the knob the volume will first jump to max. This can result in som scary lollipop (pardon my French).
Using the mixer volume, by turning the little knobs works great because these just adjust the volume frome wherever it is set.
I wish all the knobs on the POD worked like that.
Anyway, using both channels would mean adjusting both channels in the mixer so when I don't need the two paths I put everything in Path A for this reason.
yes of course yours can seem a good reason for doing this
and you're not saying that you do it because it sounds better... 'cause it doesn't
indeed it's exactly the same, I mean exactly...
I imagine that you mute the path B and center the path A pan, right?
well what I'm telling you is that if you move all yor effects in pre and post path and put the amp in its default position keeping the same fx/amp order
(and leave the B fader muted and the path A pan centered)
the sound will remain TOTALLY unchanged as long as the input settings are at their default (or guitar/same)
and you'll still have you single master fader
see? no need to go so far from the default, that's all I'm saying here
just try it on a copy of your patch, save it and compare them
