If I'll be arround in this world, I'll still be spinning some records for sure.
Not sure on which TT, but I bet I have plenty enough to play with: 2 TT's in main rig Michell/Technoarm; Empire 591/AT 5001; 2 Technics 1200 MK2 - stock arms and 2 Technics 1210 red/blue duo color with stock arms for parties. I DJ on 4 TT's at a time: 2 have scratch setup and 2 have playback setup
DJ digital playback usually used for breaks with pre-mixed sound effects.
Will there be any old-school DJs in 25 years? Why Not?
Who knows, maybe Technics or other brand will come up with even more versatile new model for DJ turntable... 25 years isn't too far to the future and one will know where to find mechanical analogue media among the digital clouds.
