This EQ is equally suited for tracking, mixing and mastering. It is intended as a primary EQ that you can use as a first choice for almost everything. It was also designed to sound different from other EQs so as not to be just a slightly differing flavor from your current parametrics and console EQs. Vive la difference. But it does have 3 knobs per band, if that is your definition.
Interactions are natural and part of real life and the physics of sound and music.
Some mastering engineers prefer rotary switches because it allows him or her to return to near exact settings of a previous session. There are two other valid reasons for detented switches, rather than pots. Some audiophiles claim that a gold contact switch with precision resistors seems to sound slightly better than conductive plastic pots. A true parametric implies non-interacting controls. Conversely at the widest bell, the maximum boost or cut is 6dB and the narrowest shelf maxes out at 12 dB. A similar situation is also true for the bandwidth detents.
