Stuff like this is EXACTLY why digital had such a bad rap for so long.
Newb to old grey beard: "Look at all the cool tricks this thing can do -- and I've got the portability of the Spark Go but can plug into this thing for when I need to be loud"
Old grey beard: Turns volume knob up; sound goes to shit; is very loud in newb's bedroom but still not as loud as he'd need for any kind of jam that involved a drummer. Everything turns to crap.
Newb: "WHOA! That's REALLY loud! See how Awesome it is!"
Old Grey beard: "Wait, you paid $420 for this rig? You should have gotten a used [insert appropriate boost/od pedal for genre] and [insert appropriate 20 year old budget tube combo] for that kind of money. Would have been way better."
Old grey beard is right if the newb does actually wanna play with others. Newb probably should have just gotten a Katana or a Katalyst depending on genre.
