So many variables Ped. Some gigs I play a very nice Ray which I think sounds great on stage and off, whereas other gigs I play a Mustang which is far less distinct and wooly to my ears. The drummer's partner, who comes to most gigs much prefers the Mustang - so she can tell the difference but disagrees with the assessment of the player.
The venue is also a massive factor - different pub, different sound.....and can't always be fixed by the soundman or the bass/amp combination.
