These amps sound better than amplitube or Jamup and there are plenty of amps to choose. The effects are limited however. The effects are enough to make the app useful but I can't get every sound I want. I should mention that the effects in amplitube and jamup aren't much better. Those two apps have three times more effects to choose from but the sound quality isn't as good. The line 6 effects are a minimal set of reverb chorus eq compression, just one effect on each category and limited options on each. I like the idea of just having one version of each effect. I'd much rather have one great reverb than six cheap ones. The reverb in this app is better than anything in amplitube but it isn't great. So at the moment, if I had to choose one iOS amp sim app and gig with it, line 6 would be my choice.
