IznremiX has it right on the money. See if the club has gear you can use.
However, and not to sound like an “old fart”, but “back in my day” we used what we had. I played parties with cheap belt drive tables and a crappy Radio Shack mixer. You guys need to stop thinking you can’t play because you don’t have an S4 or something like that.
You have the means…use it. Wow them with your set. If a club or promoter is going to ignore the great set you play and totally judge you on the gear you own, then it speaks volumes why he won’t last long as a promoter.
