7. MODE Switch
Used in combination with the COMPRESSION knob (8),
this switches the compression effect type.
STANDARD:
This produces a compression effect like that used in
recording studios.
TUBE LOGIC:
This provides the natural, fat compressed sound typical
of tube amps. This characteristic sense of harmonic-
induced compression is like that produced by slightly
overdriving a vintage tube bass amp.
8. COMPRESSION Knob
This is an effect that compresses overly high signals
while boosting lower-level input.
Turn the knob to the right increases the compression
effect.
Turn the knob to the very left to bypass the compression.
9. BASS Knob
Adjusts the tone quality of the lower range.
10.MIDDLE Knob
Adjusts the tone quality of the middle range.
11.FREQUENCY Knob
Adjusts the frequency of the middle range.
12.TREBLE Knob
Adjusts the tone quality of the upper range.
13.TWEETER Knob
Adjusts the tweeter volume.
This knob affects the tone quality of the range higher
than that of the TREBLE knob.
No sound is output from the tweeter when this is turned
to the very left.
* The TWEETER knob affects not only the sound of the D-
BASS speakers, it also affects the PHONES, LINE OUT,
BALANCED OUT (when the SELECT switch is set to LINE),
and SUB OUT jacks (p. 12–p. 14).
14.EFFECT BLEND Knob
This adjusts the balance of the mix between the effect
sound from the external effect connected to the EFFECT
jack and the direct sound.
fig.01-01a
The knob settings can be adjusted to accommodate for
both series and parallel connections.
MODERN
Models the wide-range sound of tweeter-
equipped bass amps in use since the ’80s.
This amp type produces a dynamic tone with
a good balance of low-end presence and clear,
open highs.
Perfect for slap bass.
Creates an aggressive tone in which the pres-
ence of the lower range and the transparency
of the upper range are greatly augmented.
