Thanks for the replies people
I am looking to gig with it, but also recording and rehearsing.
I need great tone, versatility, durability, reliability and ease of transportation/set up - in my work I have a lot of styles to cover, and for my own pleasure I need some great high gain lead sounds.
The Alchemist only has reverb and delay - both sound pretty good but I would prefer the flexibility and control of having these effects on a multi fx.
The GSystem is nearly as much money as an Axe FX, so if I was to get either it would be the Axe.
I am still super tempted by the Axe - work is buying this gear for me, but are being a pain in the ass by not letting me know a ball park figure for budget.
What I may just do is make a few set up lists, itemised, take the 'dream' rig in to the Boss, and if he laughs at me and makes me lower my demands I'll take the next lower option in etc.
