Agreed. Many sound engineers don't understand double bass at all. They want to pump up the volume and the bass end, or they add HF to cut through the mix.
On the odd occasion I get to play through a large sound system, I always send a signal with an HPF set quite high to take out all the low end. (Fishman pre)
There was one time I didn't do that and had so much sub bass I may as well have been playing D'n'B !
