The last knob - Tone - is a classic, passive tone knob
that solely darkens the tone of the instrument. One shall
note that it can be used in both ac ve and passive modes
when the Volume knob is li ed (pulled). The tone knob,
fused with the ac ve EQ, is a very crea ve tone-shaping
tool, as the output signal can be adjusted by two tone-
shaping systems, paving the way toward an en rely new
area of sound/tone design.
Passive mode
In certain circumstances, the use of ac ve EQ may not be desirable - during studio work for
instance, or when using an expansive pedalboard that offers a range of tone controls that
remain far more precise, or in situa ons when we use several instruments (including ones that
are exclusively passive), and we want all of them to retain their own, natural tone.
In the passive tone, the Tone, Volume, and Balance knobs all remain opera onal.
Musashi Preamp Variants
Depending on the model of the bass, one of many available Musashi preamp variants may be
used. The above refers both to the number of knobs (separate bass and treble knobs, no balance
knob if a single pickup is used, no passive tone knob), as well as the availability of extra
func ons, such as a mids knob with a push-pull pot, where rapid change of frequency between
400 and 800 Hz is available.
In some cases, one or two mini toggle switches are used, for different func ons. When one
of the Musashi preamp variants is used, please refer to the relevant manual.
Switching the Preamp Power On
The power switch is integrated with the 1/4-inch output jack. The preamp
is turned on once the user plugs in the 1/4 inch jack to the input socket, and
this is also signaled by a blue LED being turned on, on the backplate,
designated ON (see the image on the right).
Note: The headphone amp features a separate power switch, integrated
with the 1/8-inch headphone jack. The headphone amp is only turned on
a er the headphone cable plug is inserted into that output.
