Ive been doing alot of premastering for a reggae disk cutting room. I don't pretend to be a lathe operator, but I work with one closely. Ive learned ALOT from those guys regarding bass
. The mixes that come in are all over the map. I use a z-sys digital EQ in MS mode pretty often to reduce the lows in the vertical channel. I prefer a shelf to highpassing the vertical like an EE does. the frequency is program dependant and varies greatly, as does how much, if any, cut I apply. alot of the time the lateral gets a bit of bass boost to compensate. by the way, the cutting chain here ALWAYS has the EE and vertical limiter bypassed, but the neumann HF limiter is used. hope that helps!
