Yes Ive seen the vids but alot of them that Ive seen seem to switch to direct in when using the helix amp models,Ive watched a line 6 rep demonstrate it on andertons you tube and he had it straight in to a fender amp BUT was only using the the helix like an effects board when he used the modeling part he switched to a powered 10 inch pa speaker whic is why im still not sur eif I can still get good modeling sound in to a reg amp or is it better ti just buy a power amp with speakers,sorry if Im still not sure but I would love to see someone play model amps thru a amp.I read that the signal might be to hot to go into a reg amp and it wont sound good.https://www.youtube.com/watch?v=KdFFZBN8xL0
