I compared a g major 1 to a gsp1101 a while back in my mark iv. The gsp had some more interesting fx, like tape delay etc, but the g major was more transparent and sounded more 3D compared the flat sounding 1101. I presume the gmaj2 will be the same if not better in that regard. Also it took a watch grand national live the levels right, so the volume with and without the units engaged was at unity. But doing that is key.
