There's nothing "wrong" with them. I think they suck all the life out of a guitar, and the sound you get is a digital mess, but it's a relatively inexpensive solid state combo from Line 6, so what else do you expect?
they don't come with a built in Search Bar....
Not bad for the price.
Decent unless your some kind of "warm" "organic" tone freak

Just check it out, see if you like it
