Gday Jblob, No worries!
I use the Radial JCR reamp box which I love and for my DI box I use a DAP. But if you are trying to get some reverb on tracks that have been recorded by microphone, then a DI box will do fine. I only really use the reamp one if I’m wanting to add effects from an amped instrument (elec guitar, bass etc). You just go from an out from the back of your interface then into your pedal and out again to your DI box and straight back into you interface input, (instrument level).
cheers
