I wouldn’t let equipment issues throw you. I haven’t DJ’ed in clubs since the digital DJing revolution, so maybe what I say doesn’t matter. However, in my vinyl days, I got used to showing up in a club and taking whatever mixer they had. I’ve found that after a bit of confusion on the first one or two mixes, your natural beatmixing and song selection ability take over.
One of the biggest gigs of my life (I was the warm up DJ for BT) was on a mixer with no crossfader or sliders!! I discovered this after my first record was playing. Man that freaked me out, but I didn’t have time to complain or find another solution. My only option was to learn, and learn fast. Even so, after the initial confusion, I adjusted, and started enjoying the music everybody was really happy in the end.
