Multiplexer versus Using Scenes to turn FX on or off?

[j20056]

say I have this preset:
row 1: Phaser
row 2: Flanger
row 3: In1 -> amp >cab > out1

Lastly, Phaser and Chorus are wired in parallel just before the Amp block.
One way to select Phaser versus Flanger is to use a Multiplexer block before the amp and have two scenes that select channel A or B of the Multiplexer, itself set so that Channel A uses Row1 and Channel B uses row 2. This appears to be the recommended way of doing this.
But how about more simply having my scenes to turn on or off the FX block that I want to use or mute? As long as I set the Bypass mode to be Mute (and not Thru), then I should get the same result.
So for this use case of FX blocks in parallel, what does a Multiplexer do that cannot be done without it as described above?

Nothing. Easier to just set the bypass modes accordingly and just use bypass. I would also add that unless you need to run Phaser and Flanger at the same time, there's no real benefit to routing them in parallel. Just put them in series and turn on as needed. Multiplexer is more useful when selecting between several rows and you only ever need one row active at a time.
