Marshall VBA400 400W Valve Bass Amp Head
VBA stands for Valve Bass Amplifier and who better to make a bass amp powered by valve
technology than Marshall Amplification? Over 36 years of designing and manufacturing world
renowned high quality valve amps has given us priceless knowledge, experience and insight in
the world of valve tone.
The VBA400 gives you 400 Watts of Marshall valve power courtesy of 12 valves; 8 6550 power
valves, 3 ECC83 classic Marshall pre-amp valves and 1 ECC82 valve.
In addition to great tone, the VBA400 combines a number of other exciting and useful features.
Situated on the rear panel of the amp is a Tuner Output which allows you to keep a tuner in line
at all times (the bass is still plugged into the input on the front panel). Should you want to tune
up during a live situation in silence, simply press the Tuner Mute facility button and both the
sound to your speakers and to the DI will be cut off.
All valve amps need to be connected to a speaker before use and failure to do so will result in
serious damage to the amp. To ensure that you do not damage your VBA400 by inadvertently
forgetting to plug your amp into a speaker, we have designed the unit so that power cannot be
applied internally unless it is connected to a speaker.
The VBA400 also features an instant overall tonal re-shaper in the form of a Contour control
which has three pre-sets to allow you to dial in three different characters in an instant.
