Software is easy to use but will take time to explore all the options.
I purchased iRig UA was released but didn't care for the app as a portable headphone app that much the amps seemed... meh. I am on an extended stay out of town and wanted to do some recording. The cheapest and low footprint option was Amplitube.
First impression is WOW!!! I don’t seem to miss my Blackstar amp as much. The amps are realistic and have the sponginess and sag I was missing from the amps in the Amplitube Android App. Then again the Android app was free so you get what you pay for. On the other hand Amplitube 4 well, I didn't expect tube like sound from a program; IMO lifelike and realistic.
The effects are usable and pretty good as well. The sound is much better than any Line 6 product I have used or owned and for a lot less money too.
Interface is impressive from setting up effects loops and effects chain, (Amp options, Rack effects, Speakers, Cabinets, and Mike options).
The Looper or Recording options are great but, haven’t used it much yet….the reason I acquired this. I am having too much fun playing around with the amps. My impression is this is great for the bedroom musician or someone that doesn't have space for much gear to the budget recording studio or a traveling person like myself. Everyone from all walks will like it if not love it. Great substitute for the real thing as long it is not live on stage.
