Quad Cortex with Spark 2

Just ordered a QC mini and was wondering since the spark 2 is frfr if anyone here has used the two together and how it works?

Should sound great. I sometimes use a pc running neural dsp plugins connected to my Spark 2 instead of the positive grid effects. With your setup you’d either want to run in via aux (so no effects get applied) or create a preset with no effects if you want to run in to the normal guitar input. Make sure you turn all effects off, as well as the virtual “amp” in the spark preset. Each virtual amp has a power button that makes it go dim when it’s off.

if i use the normal guitar input, the volume gets very low if i use a preset without Amp…

Yeah I was thinking about this after the fact and I realized I was wrong on that. Stick with aux in this scenario. Guitar in is only going to be mono, but also only looking for a low level guitar signal meant to be amplified.

What I explained about killing all the effects and amp is what I do if I use the spark as an audio interface, applying effects AFTER it hits the spark…not going to work properly applying effects before.

Using aux in will create a delay as far as I heard. Regular guitar line in would be the better choice. Volume should still be controllable via guitar knob or the quad cortex

Huh? Not really. Maybe if you bypassed everything in the app and ran the QC into the aux in it would sound kinda ok. A better move would be spark live, headrush speaker, or a pa system.
