The Effect of the Shape Control

The Hydrive's unique Shape control enables the

sound of your bass instrument to be enhanced at

the touch of a button. When the front panel Shape

switch is pressed in, a special equalization curve is

activated that is designed to improve the sound of

most electric bass instruments. This curve provides

moderate boost at certain frequency areas and

deep attenuation at other frequency areas. Further-

more, the front panel Shape control adds a filter to

a selected frequency area within the Shape curve.

As the Shape knob is turned clockwise, the filter is

imposed on higher frequency areas; as it is turned

counterclockwise, the filter is imposed on lower

frequency areas. At the fully clockwise position, the

filter is applied to the 1 kHz frequency area; at the

fully counterclockwise position, the filter is applied to

the 80 Hz frequency area.

Even when Shape is activated, the front-panel EQ

controls remain operational. When all EQ controls are

set to their “0” (flat) position, they add no boost or at-

tenuation to the preset Shape curve. However, when

any EQ controls are moved from their (“0”) position,

their boost or attenuation effect is superimposed

upon the preset Shape curve. In this way, you can

customize the sound of the Hybrid combo further

still to complement your particular bass instrument

and playing style.

Note that, when the Shape switch is out, the EQ con-

trols operate on the “flat” signal coming from your

bass (that is, there is no preset equalization curve

imposed).

For expanded control on stage, you can use the op-

tional FS2 footswitch to select the Shape on or off.
