Any experience with zoom g3xn, especially gigging?

Voxman

Not the older g3x but the new grey version.  Effects speak for themselves so no need to comment on the quality of these and choice, but I'm particularly interested in your views on the quality of amp modelling, ease of use and switching for live use.  

These have really come down in price and at £127 new (Bax £126 with 2yr warranty) these seem to be fantastic value.  

As much as I love my Tonelab SE it's a big, heavy unit and it would be nice to have something that sounds good, is easy to use on stage, and is small and light.
