When it comes to designing and producing valve
amplification, nobody does it better than Marshall. Hence
the logical extension to the Marshall range of valve
products to include a high-powered, professional valve rig
for the bass player. Valves bring with them a unique tone,
feel and response and these attributes are just as attractive
to bassists as they are to guitarists. The warm, deep tone
of our VBA bass rig, not only expands and enhances the
sound of your bass in the live situation, it also adds a
unique, 3-D quality to recordings. This stunning bass
set-up has won many converts since its introduction –
here’s an insight into what has made it so popular.
400 Watt Valve Bass Amp
The Marshallname, togetherwithour famous scripted logo, has always
been synonymous with world-class, valve-driventone. Inkeeping with
this tradition, our 400 Watt, all-valveVBA400 bass head is being hailed
by players and press alike as another true classic.
Designed with the serious bass player in mind and drawing from our
many years of valve ‘tone crafting’ experience, the VBA400 boasts a
staggering 8x6550power valves, plus 3xECC83 and 1xECC82
pre-amp valves.
One of the main things that makes this amp specialis the sheervastness
of pure valve power on tap from the twelve valves it houses.
Consequently,we didn’t want to dilute any of this natural purity by
incorporatingunnecessary features and controls. For thisvery reason,
only the essential front panel controls have been included.
This said, the VBA400’s3-bandpassive EQ networkfor Bass, Middle and
Treble has beendesigned so that it offers you all the tonal adjustment
you’ll need.Furthermore,thistonenetwork can be totallychanged by
means of the 3-position Contour switch whichreconfigures the mid range
as follows:
Contour Position 1 – drops the low mids and creates a rounder, fuller,
fat bottom end.
Contour Position 2 – boosts themid range, givinggreater edge and
aggressionto your sound.
Contour Position 3 – moves the mid range higher thanyou would
normally expecton a bass amplifier. This adds an aggressive twang
while leaving the essential body of your tone intact, making it ideal for
percussivestyles such as slap bass.
Further tone control is provided by Deep and Bright switches.
Engaging the Deep switch increases low-end thud without losing
definition while the Bright option adds extra high-end brilliance and bite
to your sound.
Other essential features include Active and Passive inputs, an XLR DI
Output, complete with switches for Earth (ground) Lift and pre/post EQ
selection, a Series FX Loop and a High/Low Fan Speed switch to
ensure the valves are kept at a safe operating temperature.
Another very practical ‘bassist friendly’ addition is a Tuner Mute facility
which, when activated, mutes the signalto both the loudspeakers and
the DI Output, enabling the user to tune ‘silently’in the live situation –
providing a tuner is hooked upof course!
VBC412 & VBC810 Cabinets
Specially designed, heavy duty,matching cabinets for the VBA400 head
are available in 4x12" and 8x10" formats. Builtas only Marshall knows
how,both feature separate sealed chambers (four in the VBC810 and
two in the VBC412) which help to prevent unwanted cabinet resonance
while addingto the structural integrityof the units. They are also lined
with sound absorbent wadding to further help dampen internal
resonance.
Both cabs are loaded with custom designedloudspeakers which have
been specially voiced to handle the power of the VBA400’s output while
giving you superb, professional performance.Bothcabinets operate at
4 Ohms impedanceand have been designed to perfectly complement
the VBA400. As the amplifier will accept aloadof 2 Ohms, combinations
of the twocabinets can be used to create an awesome bass rig.
Clad in Marshall’s trademark, heavy duty
black vinyl, the 400 Watt VBC412 and 640
Watt VBC810 each boast roadworthy, high
grade fittings. The VBC810 also features a
recessed handle on the bottom for easy
lifting, castors and an aluminium kick plate for
easy tilt and roll capability plus aluminium
edge protectors.
