100% agreed with Elantric. I had the G3X.....and have 2 MS50G's(same as MS100BT but without ability to add additional amps and models thru bluetooth purchases). Using these pedals is like trying to use a full professional version of Protools in a mobile phone app.(hypothetically). 100% goodies- 5% ability to use them. If you opened one up it would explode software all over the room. Really no practical use live unless you only need some basic settings and effects and don't mind having to make changes by hand during a gig. In a studio, if you want some good effects or models and need say a particular amp model/sound for a track, and want a few effects to tweak the sound, it is probably fine. In a nutshell.....good amp/effects models, but very little function for any real practical on the fly use. Think of it as a MFX processor without a foot controller or midi. There are better options out there. For instance, you could get a used Boss GT10 for about $100 more and go from driving a VW to a Mercedes. Just my 2 cents.
