Never heard of Robot! (and their blurb says it set the world on fire last year!!)
I am a Line6 variax owner (less of a user since I discovered the joys of buying too many guitars and installing BKPs :lol:).
The variax is a fine idea, and if you don't/can't own the guitars modelled, it does a pretty good job. But there are too many mechanical things inside that can go wrong (loose or dirty connections, etc) for me ever to trust it enough to take it out live. And if you've got a real strat with ITs in, the "Spank" model turns out to be sh1te in the end, and if you've got a nice Love Rock with Mules in, the "Lester" models are sh1te, and... need I go on? :lol:
But basically I quite like the variaxes, they do a superb job for what they are, but I prefer my real guitars... (I still use it when I want to record "accoustic" or "Coral Sitar" parts - but I don't do any recording because I'm too busy playing blues licks and adjusting BKP pickup heights, trying different strings and plectrums, gassing about more guitars, etc, etc...)
But this Gibbo beastie doesn't appear to have modelling in it like Variaxes do, just the piezos and various blending with the magnetic pup configurations (Line6 could learn from that - stick a real pup on for when your onboard computer cuts out mid gig!!).
I can see uses for that configuration, and I can see some really going for it, but it's not for me. Feline's just built one hasn't he for one of our chaps here? (I even saw it before the hardware went on - very cute looking beastie). Not a bad idea at all, but how many people actually want that to warrant a production line? I can't see them competing with Line6's market, but Line6 seem to be losing their way a bit anyway...
But what about this robot tuning though??! It really made me laugh... Does it actually work? What happens when one of the servos breaks down and you've forgotten how to tune by ear? Or you're in the middle of a song, and you've no idea what tuning it's given you...! :lol:
