?? is it just me or does it seems like it wouldn't matter where u slide your fingers off from, side or top.
just focus on getting the timing of the gaps inbetween each click to sound right.
like u dont want the gaps real short and fast on a track where it makes more sense to have smoother slower crabs. and vice versa
also FYI i slide off the top of the fader cap. but i really dont think it should hinder the sound as long as the clicks or timed good.
