After my tests i noticed. Studio direct in output settings POD HD is the best sounding mode. The rest is weak! Even for the live settings (no cab option). Line 6 better give us global equalizer in output mode, like a eq in POD XT (this little 4 band bastard make every wonders and brings POD to live). Heavy sims mesa, bogner, engl they don't have a balls. Stock eq's in preamp is muddy and harsh, not bassy and shiny! L6 please change it!
By the way. On headphones i got superior tone in 5 sec.
I apologise for my weak English :)
