Operating the Bass Attack
Using the HARMONICS control The Bass Attack provides a HARMONICS control for adding overtones, which produce a tube like tone. The HARMONICS control allows you to add a little warmth to your sound, or dial up complete distortion for a radical roots rock sound. When using the Harmonics circuit, keep in mind the BRITE control is turned on with the HARMONICS (using the ON/OFF footswitch), and will affect the sound. The MIX control is also active to adjust the balance between clean and effects. � � � � Switch the ON/OFF footswitch so the red LED is illuminated, indicating the HARMONICS circuit is engaged. Now adjust the HARMONICS control to set the amount of overtones. Next, use the MIX control to adjust the blend between the clean signal and the Harmonics. Adjust the BRITE control for more high frequencies.
Using the SHAPE control The SHAPE control applies a specialized 20 dB notch filter to the specified frequency area so that you can customize the effect of the Shape curve to best complement your particular bass instrument. Moving the Shape control clockwise causes the notch filter to be applied to higher frequencies while moving it counterclockwise causes it to be applied to lower frequencies. At the fully clockwise position, the filter is applied to the 1 kHz frequency area; this will act to attenuate mid-range frequencies and give your bass a deep, low tone. At the fully counterclockwise position, the filter is applied to the 90 Hz frequency area; this will act to attenuate low frequencies and give your bass a biting, trebly sound. � � Switch the SHAPE footswitch so the red LED is illuminated indicating the SHAPE circuit is engaged. Now, sweep through the frequencies and find the Shape curve that�s the best for your sound.
