The scratch echo (technical fader) :
This scratch technique allows you to reproduce the effect of an echo as its name indicates. So it is with the fader and not the crossfader that we will proceed to make the scratch echo. Usually we look at the marker on the vinyl, but for the scratch echo you have to concentrate on the fader position.
Above all, you must be comfortable with the forward scratch to perform this technique. Then you have to be precise with the fader otherwise the desired effect (the echo) will not be produced.
