Nobody, but nobody has ever commented on my rig. They comment about the band, yes all the time, the basses very very occasionally*, but not the rig. Apart from the rest of the band, when we're loading and unloading. Then they say "I'll carry your cab, you take my kick drum/PA cab/combo...". All the time.
