Awesome! Line 6 has done it again.

Great product and clean sound.

One Word - Phenomenal!

I expected to hear the same trashy sound I got from other so called iPhone amp sims (I paid over 65 bux for that ONE that looks so cool that is supposed to be tubelike), you cannot beat this. Go buy one, hell go buy several and give them to friends. It is really really good. Ya got it right this time Line 6. This thing actually sounds better than my XT Live, no kidding.

The One To Beat

I've tried all the other iPad/iPhone-based sims and found them lacking in one way or another--Amplitube doesn't accept Core Audio so the sound quality suffers, and there a very limited number of presets. Ampkit sounds better, but you end up getting nickeled and dimes in order to build up a decent collection of virtual gear. IShred lacks amps and versatility. Line 6 was listening. A huge selection of gear with no add-ons to buy. Great crystal-clear Core Audio. A ton of presets including access to an online library. This sounds so good running the output into a Fender Champion 600. Only flaw is the interface won't accept the power cable so you lose charge fairly rapidly while playing.

Better with help!

My biggest problem with this interface is it doesn't stay plugged into my iphone/ipad. I ended up buying a 2ft. dock extention cable. Another complaint is that you can't record from the line 6 app. The biggest pro for this is that that it does interface with the dock port and not the headphones. The sound quality is really good for what it is.

It's classic Line 6. It falls short.

As mentioned earlier, the unit does not have a positive feel when connecting to the port and you still end up using a 1/8 line to run to a mixer. I found the sound compressed and lacking dynamics although I don't blame the mobile in. I opened Ampkit while using this interface and it sounded great. Very natural. It's not going to replace your Axe Fx, but it's a useful practice tool.
