Zac, I think it would grow on almost anyone... with the usual (but easy to do) tweaking for your particular guitar / style / preference, JamUp can sound as good as ANY modeler. Hardware or software. A member of a JamUp Users Group that I belong to claims to have a Kemper and POD HD 500, and to have had an Axe-FX and agrees with me... in fact, he wrote a post stating exactly that.
Nothing against the 11R - it's a great piece of kit, and very pro, but I truly appreciate that I can get the sounds I do out something as small as an iPad Mini or even an iPhone.
P.S. Zac, I'm curious... which patch did you find on ToneCloud? Did you like it?
