I tried pretty well every high end amp modeler out there, except the Eleven Rack. The only one I bonded with was the GSP1101. I like GR5 better than any of the hardware, but it is still to buggy. Was gonna buy a Helix, but the lack of midi clock sync to my DAW, and all of the bug reports in Line 6 forum, turned me off. I don't think the Helix was quite ready for the market. I ordered a new XL on Sunday and it should be here on Friday. The price was hard to swallow, mainly because of exchange rates with the US dollar. Line 6 Helix...you loose! Bought a frakin Fractal!
