Pop a string on that thing and it looks like it could take a long time to replace, and you can't just grab another guitar off the stand behind you to quickly change without another fusion guitar plus another IPhone etc.
Just saying, it could be a nightmare in a live band situation.
I do also Play guitar as well as my S950 in a full 6 piece band and have used jamup pro and think it's pretty good, but don't need it built into a bulkier sized special guitar.
