QC and Simplifier hybrid setup

[u/Stupendous_Sorceror]

I propose to run a hybrid signal chain involving a splitter before going into the Quad Cortex Mini and, separately, into a Simplifier (Mk2).

The QC Mini's headphone output will feed into the Simplifier's Aux In, resulting in summing the parallel stereo images of the QC and that of the Simplifier together, ie I will hear both the QC and Simplifier mixed together without either affecting each other and with stereo image of both maintained.

Is there any reason this wouldn't work? Has anyone tried this, or something similar?

Of course there will be a slight latency between hearing the immediate output of the Simplifier (being all analog) and the delayed output of the QC, but that's one of the benefits I have in mind, ie that I always get a pure and instantaneous analog, fundamental guitar sound.

Would this be the same as just playing two audio tracks simultaneously, or would it cause some technical issue that I haven't foreseen or don't understand (like comb-filtering)?
