The real concern withe the Headrush is the latency. 14ms, which stacks as you add captures/clones/profiles.
No bueno.
14ms is when you use a "clone", not with a built-in amp. How they released it with that glaring of an issue is beyond me. Will they fix it, who the heck knows with their history.
I do really like the "practice" based features, though. On device loading of backing tracks with slowdown and pitch change abilities! That alone makes me interested. Also they've shown drawings of a "tablet" connected, which is crucial for this older guy so I don't have to reach down to the floor 100000 times for tweaking. If they actually activate the "tablet" feature and fix the "clone" latency, I may start to gas.
