Bass Amp Designer offers an additional Graphic or Parametric EQ that you turn on with the EQ switch above the Master knob at the far right. The Parametric EQ provides two EQ bands:
HiMid: Controls frequencies in the high and high-mid range.
LoMid: Controls frequencies in the low and low-mid range.
Type switch: Click the up position to choose the Graphic EQ. Click the down position to choose the Parametric EQ.
Graphic and Parametric EQ parameter settings are retained when switching between EQ types and when the additional EQ is turned off. This allows quick AB comparisons.
Pre/Post switch: Click to determine if the additional EQ is inserted before or after—pre or post—the compressor section within the signal flow.
Note: This parameter is relevant only if the Compressor is turned on.
Gain knobs: Adjust the amount of cut or boost applied to the frequency range set with the kHz knob.
kHz knobs: Set the frequency range you want to cut or boost with the Gain knob.
Q knobs: Set the width of the band surrounding the frequency set with the kHz knobs.
The lower the Q knob value, the wider the band, which means that more frequencies are affected. The higher the Q knob value, the narrower the band, which means that only the frequencies nearest to the frequency set with the kHz knob are affected.
