After all theses years...

Straight in….to my Kemper :p
Not exactly 'old school' there, pal!

I mean...that's straight in all right...straight into a pair of A/D converters, then to to a model incorporating an IR of a different amp (in other words a recording of that amp), which is then digitally processed, and then out to a D/A converter, and through more analog circuitry.

Kind of a stretch to say it isn't a more processed sound than using pedals in front of an analog amp.

On the other hand, if it works for you, then my goodness, it works and more power to ya! ;)
