I have been using NI Guitar Rig for quite a while and want to make a change. I preselected the three above.--Real amps is not an option for me. I have read many good things about the new Helix LT. However, I mean, in the end of the day it is a small computer inside. And, I wonder how much better can it then really be than one of the other two? I would like to read/hear some opnions and experiences pls.
