All other controls on both versions are switched for repeatability.  The high pass filter of the mastering version offers smaller steps and varying filter slopes to that on the recording version. \u003cbr\u003e\u003cbr\u003e Taking a look inside the REQ chassis you will discover a very high level of engineering and build quality with single point power supply wiring, discrete power regulators for each band, reliable ITT rotary switches and Alps rotary boost\/cut pots (or Elma stepped attenuators in the Mastering version) - the list goes on and on.
