I just received my power rack yesterday and am getting a Matrix NL212 next week. Initial thoughts are very positive, and I'm looking forward to spending some time getting to know the unit (when my 2 year old gives me some time off!). Reading the posts on here I gather there's both a rig manager for Mac and a footpedal on the way sometime soon (ish) which will be great. In the mean time I have a Roland footpedal I can hopefully use. I've been using a Mesa 5:25 and a bunch of pedals up to this point, but I got sick of lugging everything around, so a big part of the appeal for me is the portability and weight reduction.
Anyway, looking forward to joining the community!
