on the FBQ display. For example, if the sound is muddy or booming
at 160 Hz, this is shown by a brightly lit LED in the corresponding
control. Move the 160-Hz control down a bit (negative range) to
eliminate the booming sound. Conversely, you can accentuate
certain signal ranges that lack presence (LED lights up only
faintly) by moving the relevant controls upwards.

You don’t have to raise the volume of a frequency
range to make it seem louder. Instead, you can
lower the other frequency ranges by moving their
slide controls downwards. This prevents the
internal signal level from becoming too high and
also gives you some valuable dynamics headroom.

3.2.2 The Shape function
The Shape function on your ULTRABASS provides a
revolutionary type of filter that you can use to modify your bass
sound completely. The filter allows you to shape your sound—
which is a must for bass players today. Extreme filter settings
will give your bass sound more punch, for example:

will give your bass sound more punch, for example:
You want to play a live bass solo but the sound doesn’t cut
through. The solo should stand out, rather than being drowned.
First, set up a solid basic sound on channel 1. Then, create a
very distinctive solo sound on channel 2 using the Shape filter.
Since the Shape filter is only effective on channel 2, you can
change sounds quickly and easily before you begin your solo.

change sounds quickly and easily before you begin your solo.
The Shape filter is worth its weight in gold when you are using
two different bass guitars. Maybe you want to change from one
instrument to another with a completely different sound. During
gigs you often lack the time to set up your amp for a different
instrument. Because you can use channel 1 for one instrument
and channel 2, with its Shape filter, for another instrument, you’ll
be glad to have the ULTRABASS.

3.2.3 The Ultrabass function
In current music productions, extremely low bass sounds that
are one octave below the lowest available bass guitar frequency
are quite popular. Often, you can only create this sound in studios,
because most bass amplifiers have no sub-harmonics function.
This is not true with the ULTRABASS. The Ultrabass processor
gives you the ultimate tool to shape this contemporary sound.

This is not true with the ULTRABASS. The Ultrabass processor
gives you the ultimate tool to shape this contemporary sound.
You’ll be amazed to hear how deep your bass can sound with
the Ultrabass function. Extreme settings can be particularly
interesting if you want to give your sound added sparkle in the
treble range. By the way, if you already set the Shape filter to
create punchy sounds, but feel that there’s not enough power in
the bass range, the sub-harmonics processor is there to help
you. Even if the sound is still punchy, it will have much more depth.

The Ultrabass function can be controlled with the supplied
footswitch, in order to emphasize certain passages, for example.

3.2.4 The compressor
A compressor is used to limit the dynamic range of a signal.
Signal peaks are lowered and soft signals are raised in volume,
thus reducing the difference between the highest and the lowest
signal levels. The result is a much more powerful sound.

Some playing techniques, such as slapping, lead to high-level
differences. In this case, a compressor can be used to make the
low-level dead notes clearly audible, which gives the bass line
even more groove. What is more, the sustain of long notes is
extended.

Compressors work best if provided with high input signals. If the
signal level is low, the effect will be activated only with high
settings. If so, enabling the compressor can lead to extreme
level differences. If GAIN is high, the compressor comes in quite
early. In this case, you don’t need to turn up the COMPRESSOR
control that far to achieve an effect. Experiment with it to find the
best setting for your needs!
