How do I use an effects loop?

I’m wondering if it’s possible to use QC effects into the loop of QC amps? I’ve found guides online for using physical effects but I’m looking to put the digital effects into the loop of the digital amps, if possible.

Sure. Easy, just put your effect block you want after the amp block or amp and cab block. That’s how I make most of my presets. Drive blocks → amp and cab → delay and reverb to the outputs. Gets you those crystal clear delay repeats and reverb trails like putting the real life delay/reverb pedals in the amps effects loop. Hope this helps.
