Sorry I am late to the thread. I have purchased and sold the G Major 2 twice . I love the effects and programming but when used in the loop of the Mark V the AD converters changed the tone of the amp too much. It always had some weird residual modulation and it took away some of the oomph from the amp.
I am happy with the Mobius and TimeLine, but I do miss the harmonizer and ease of programming of the GM2
