instructions above, your only maintenance problems should be
cleaning. We recommend a soft damp cloth and mild soap for
cleaning the outside surfaces. If you are going to pack your
amplifier around a lot, we recommend a road case to protect it
from scratches and road wear. Road bags are available from
Gallien-Krueger.
Setting Up Your Sound
Your amplifier is designed to sound about right with the tone
controls set flat (at"5"). We therefore recommend you start with
the EQ set flat, the voicing filters out, and the crossover at 500hz
("5").
Helpful Hints
1. Don't be afraid to experiment with the EQ on your bass first.
Make sure that you have as close to the sound you want from
your Bass before adjusting the EQ on your amp.
2. Set your playing level first. You may want to push up your
volume and boost levels while dropping back the masters. This
will give a fatter sound but can add distortion. Some players find
this desirable, you will have to be the judge. For the cleanest
possible sound, operate the masters near or on "10" (max). The
boost control is footswitchable and can act as a preset volume.
The LED next to the boost control indicates that boost is on.
3. You may have to experiment with the crossover point and the

relative levels of the high and low masters. It is best to adjust
them before the EQ. They should be adjusted to give the most
desirable sound without distorting the high end speakers. If the
crossover confuses you, try switching out of the bi-amp mode
and set up your sound in the full range mode first.
4. Once your basic levels are set, work with the voicing filters.
The Lo Cut is a bass roll-off and is used to control stage rumble
at high volume. Mid Cut puts a notch at about 500Hz, giving a
mellow round sound. Hi Boost adds edge and definition.
5. Having set your levels and filters you are ready to fine tune
your tone. This is an involved procedure requiring you to use
your ears to tell you what is right. We have broken the sound
spectrum into four basic bands and provided active controls for
each. Adjustment procedures are iterative and require patience.
After you have adjusted the Eq, you may want to fine tune the
crossover and master controls.
TREBLE : Boost and cut at 4KHz, will add or remove edge and
definition.
HIGH MID : Boost and cut at 1KHz. There is a lot of sound in
this band. It works on the lower harmonics of your instrument
and effects the punch of your sound.
LOW MID : Boost and cut at 250Hz. Basically, this band
effects the body of your sound.
BASS : Boost and cut at 60Hz. Effects only the bottom end and
will be used to account for varying room acoustics.
