IK Multimedia Axe I/O One 1-In/3-Out Audio Interface
I was shocked to hear the difference the AX I/O One made to my guitar sound. The Z Tone is a revelation, turn it to the brighter setting for clean sounds and the darker setting for high gain sounds and it just feels and sounds incredible. I have some good modern sound interfaces but after using the AXE I/O One I don't think I could go back to using any of them. The software bundle is good (although I haven't tried Live! as I use Cakewalk), both Amplitube and the included version of Tonex have some good sounds.
The AXE I/O one also has midi and a really useful function where you can connect a footswitch or an expression pedal and control features of your plugins. It works and is very cool.
So: a great interface if it works for you, just remember it has a single channel so can only record one thing at a time!
Enjoy
