I've had this bundle for almost 3 years.. my intent was to use it primarily for recording.. it does this amazingly well. Plus the ability to reamp... Plus the interface , plus protools full license.. now for practicality, I would not, nor would a professional guitarist strictly use this unit in a live situation.. you CAN and it will work, rather well.. but i never used this as my primary live rig., I kept it in my rack as a back up, right next to my g system brain which I used for midi switching my live rig (Marshall jvm's)... It is a preamp, and has pretty good effects.. i bought the mission EP11s expression to accompany this.. and the wahs on the unit are the best digital wah I've ever used.. way better than my g system.. but I typically use a handy jc95 live :-) my main focus in this review was to emphasize that this, for me, is the fastest and easiest way to get my guitar ideas into the box at a very high quality resolution.. I tried the 4 cable method just for giggles, and just as expected my Marshall felt more realistic and alive than the jcm patches, and my mesa sounds and feels more like a mesa... BUT straight into my daw and out of my studio monitors is where this thing shines for me.. and still has a great "feel"to it.. realistically, i know that models are getting close, but i don't think I'll ever prefer a model over the real McCoy!! I RECOMMEND THIS TO THE HOME STUDIO GUY, OR ASPIRING GUITARIST !!
