In this particular case, the sound guy is the band's EMPLOYEE. He does not have the right to dictate what pedals you use. He does have the right to work with you to get the pedals sounding good in the mix. I don't use effects, but if I did, no sound person that the band hired would tell me what or what not to use.
The band should have a vision of what they want to sound like. The sound person's job is to get that vision to the audience. It's not their job to CHANGE that vision.
