Hey there Haylo
Can’t give you any advice cos I’ve never used CDJs either and I’m a old school Technics DJ! Have a private gig coming up at a bar where the gear is pioneer CDJs too so I kinda feel what you are sayin. If you are comfortable at beatmatching by ear then I reckon you’ll be fine and besides the CDJ2000s look to be serious kit and the screens at least will probably give you some familiarity. Maybe it’s a good idea to go and download the user manual from Pioneer and read up.
For me the problem is the opposite to you cos I learned on technics and have only ever used vinyl at club gigs and that was a while ago too. Back then you just rocked up with a bunch of records. I’ve got the digital stuff now and I use it alot in my own space, and it’s all good and all, but CDJs are just somethin I’ve never used. Just gotta figure out the best way to organise my music onto USB or even CD’s and then figure it out how to work it all when I get there..ouch
Best of luck!
