I have had several interfaces the most expensive being a EMU1820, the most versatile the TASCAM 1641 for doing bands, and several others tried. Numerous other recording devices reel to reels to Portastudios. The Line 6 UX2 is different than all of them. For me this is the most enjoyable unit of all, mainly due to the Gearbox software. Ive had this about 2 years, as a second "songwriter' interface.

Gearbox is a colorful, attractive interface, easy to use guitar, Bass Guitar with selections of amps, comps, eq, noise gates etc.. sm57 or md421 sims off center front, etc... The real surprise was the Vocal Mic software that includes a selection of Mic PreAmps using Neve, API, UA and then all the reverbs and echos, compressors of several flavors LA2A, and EQ and a Noise Gates and more.

OPERATION: This is 2013 and mine is a used one, so the computer power is probably more than this UX2 needs. It operates flawlessly with USB 2.0. I use it with the Reaper DAW. It has 2qty XLR in's, the preamps are not loud at 20db, so Dynamics require full blast and noise can be heard, however, with a Condensor Mic/ higher output mic , this is not an issue. The mic preamps are very common to all the other interfaces Ive owned. 48v ready. The Gearbox Vocal Mic Preamps and array of Mic Effects make up any volume needed. All the settings can then be easily Saved, so a Warm & Clean Mic setup can be stored, or a Blues Guitar Cmp can be saved for recall....its very cool.

The Guitar 1/4 inputs have a pad the back has Line IN for drum machine, keyboards or external/outboard preamps going straight into the Convertor (AK 4528) works well. Monitor outs and Headphone out is standard 1/4.

I gave it very high marks as a "Songwriter's Interface".
UX2 works well without any outboard gear, without buying softwares and even without using the DAW effects. The other unique feature is the software doesnt use the CPU power, it is there going into the DAW as it would be if you recorded with pedals, or a vocal channel strip with eq and comp "live".

This was an interface I purchased, to get into the digital recording domain, as Guitar and vox are my primary instruments.

The UX2 is simple and easy to use. Awesome guitar tones, good bass tones, and often with my band's recordings I will run their instruments back through these virtual guitar rigs, and really beef up the sound.

A bit noisy for "some" settings. Better compressors built in would be nice.

I now use it with my Tascam 2488 neo and Abelton Live 8, and it works pretty well.

For the price, it's a great entry level product.

It doesn't have the best sound quality or conversion, and it is really meant for guitar players but less so for vocal. Vocal isn't nearly as good sounding. But you can get some great tones for guitar if you are not too heavy handed with the effects.

The Pod Farm and the equipment are great, a ton of features and as long as you are sensible about the effects you can get really good tones. Take it easy with the effects, it gets that glassy digital sound very easily, but you can get some good fender and marshal vintage tones, nowhere the real thing but really good for the money. I am not a high gain guy, but I think that is where a lot of the most authentic sounds are. But again, if you just use a marshall with a cab and maybe a boost pedal it sounds really good.

The licensing stuff with the Pod Farm setup is ridiculous and why I gave the ease of use a 3. Once it is set up it is very easy thoguh.

It comes with an absolute ton of gear to be modeled and for the money the feature set is very robust.

The fact you can use it as a vst type instrument makes Pod Farm great in your DAW, and gives a ton of recording flexibility.
