Using the Bass Attack Overdrive
The Hydrive combos feature Hartke’s Bass Attack
Overdrive circuit allowing you to add a little tube
type overdrive, some edgy dirt or all out fuzz.
The Bass Attack Overdrive operates with three
controls; the rst is Harmonics, which is used to
set the amount of overdrive.
Next is BRITE, which is a high-frequency tone
control inserted before the Harmonics that drives,
or excites the Harmonics.
Finally, MIX allows you blend between the origi-
nal clean signal and the overdriven signal.
If you want to add a little tube tone, start with all
three knobs at the 12:00 position. Slowly move
the MIX to the right adding in more Harmonics.
Now experiment with the Brite control to add
more high-end distortion. Keep adjusting the
Harmonics for even more fuzz. Often a little bit
goes a long way. You may dial up a slight bit of
overdrive and not even notice it’s on, until you
switch it o.
For expanded control on stage, you can use the
optional Hartke FS2 footswitch to select the Bass
Attack Overdrive on or o.
