As with any demo ,the product will only sound as good as the person demoing it.
The skill to demo a new product is an art in itself these days ,and guys like Paul Hindmarsh have that art perfected to a tee.
Apart from being an excellent guitarist with a wide range of styles ,he always knows the product inside out ,and presents as such.
Point being , that i'm sure DSP Neural will get some better demo's out there at some point, though maybe they've just been a bit naive ,what with being new to hardware and all that.
If i didn't already own a Helix , and was in the market for something new, from what i've seen and heard so far tbh ,my money would go on the Pod GO ,and i view it , and not the Helix , as it's current competitor.
Although the Cortex has other selling points, one of the main ones is the touchscreen, . i view a control pedal as being more important, and that makes the Pod GO a proper grab and go solution .
