I'm not sure what would be the point. Everyone knows the Noble is the gold standard but that's not what any other pedals like the bassrig are for. The Noble isn't a can sim nor does it do distortion. So again I don't think there would be much of a point.
Yes, so with a gold standard item, how do others stack up to it? If you are looking for a clean tone, does the bassrig get close? What about other pedals?
Origin Effect (and others) do pedals that are trying to come as close to a tube as possible, with its dynamics and so on. Noble has that tube, so how close are those emulations in real life?
Is it simply that when people drop $1500 on a pedal they don't want to hear that it sounds really close to a pedal 1/4 of the price? Because you often just don't get a straight answer, or even straight comparison.
Edit: Also "everyone knows" .. how? Because people that spend $1500 tell them that their purchase is worth it?
