Marshall Amplification Valvestate VS100, Handbook

10

combine this setting with heavy distortion and high Treble
and Bass settings you can get a killer ‘thrash’ tone, perfect
for brutal rhythms and vicious leads.  By turning the
Contour fully anti-clockwise you can get some great
fusion type tones.  We would suggest that you spend some
time experimenting with this control to find the optimum
setting for your style, if you’re not sure, simply leave the
control set to 12 o’clock.

15. Volume

Controls the volume of Overdrive 2 channel.

-Overdrive Equalisation-

The following Bass, Middle and Treble controls

are used for both Overdrive channels. 

16. Bass

This controls the amount of bottom end or low

frequencies in your guitar tone.  When using a heavily
distorted tone, increasing the bass will generally make
the tone darker and heavier.

17. Middle

The middle frequencies are those which generally

affect the size of your sound.  By increasing the
amount of middle in your tone your guitar will sound
fatter, conversly reducing the middle frequencies will
make your guitar sound thinner.

18. Treble

By adjusting the Treble control you can add or

take away the higher frequencies in your guitar tone.
By turning up the Treble control and increasing those
high frequencies you will make your guitar sound
more cutting.

19. Power Dimension Switch

The Power Dimension Switch is designed for use

in situations where you have set your amp to get your
sound but it is simply too loud for the given situation.
Its function is to emulate, at lower volume levels the
extra  saturation found when playing through a
transformer and valve power stage pushed to the limit.

20. FX Loop Level

It is possible to adjust the FX Loop Level 10dB

to ensure that the FX Loop is perfectly suited to the
type of effects unit that you are using, i.e. rack
mounted or floor pedal.

21. FX Mix

When using the FX Loop on the rear panel the FX

Mix allows you to dial in the desired amount of effected
signal into your overall sound.  Turning the control fully
clockwise will result in a fully effected sound, i.e. no dry
signal and turning the control fully anti-clockwise will
result in a fully dry sound.

-Reverb-

Adding reverb to your guitar tone will add ambience

and size, giving the effect of playing in a large empty
room or hall.  The VS100R, VS100H & VS102R feature
separate reverb levels for the Clean and Overdrive
channels giving you greater control over your sound.

22. Clean Reverb

Dictates the amount of reverb on the Clean

Channel.

23. Overdrive Reverb

Controls the amount of reverb on the Overdrive

Channel.

24. Power Switch

Switches the mains power to the amplifier.

Rear Panel Features

quality lead and plug are used and wired in accordance

3. & 4. Loudspeaker Jacks

minimum operating impedance for the VS100R, VS100H
& VS102R is 4 Ohms.  The internal speaker on the

external speaker in conjunction with the internal speaker,
the external speaker should be rated at 8 Ohms.

VS100R/VS102R and VS100H are three channel
