MIDDLE
Controls the midrange frequencies in your sound. Run the middle control higher to help cut through a
band mix, or generally fatten and ‘widen’ your sound. Run it lower for a lighter, less ‘in-your-face’ kind
of sound.
TREBLE
Controls the high frequency content of your sound and is also a powerful tone shaper when it comes to
overdrive character.
MASTER I
The Master I Volume control is used to set the stage or overall volume of the VX100. If this is turned to
maximum, then the VX100 becomes a non-master volume amplifier where either Gain control in
conjunction with the Volume control on the guitar allows for a wide range of Volumes & Gains to be
achieved. This can be very powerful for tone shaping.
The Master Volume control is positioned before the phase splitter valve and after the FX return.
MASTER II
The Master II Volume control performs the exact same function as Master I but allows you to set
different Volume levels and when used in conjunction with the footswitchable Gain settings, allows for
instant switching for solo boost. Master II is only activated when the supplied 2-way Footswitch is used.
MASTER I/II SWITCH
Switches between MASTER I and MASTER II. To control this via MIDI, the switch needs to be in the
centre or ‘Null’ position. This function is also footswitchable using the supplied 2-way latching
footswitch. In the ON position, this switch will override the latching footswitch or MIDI Footcontroller.
Power Lamp with Purple Jewel
When lit, this indicates that mains power has been applied to the amplifier. It houses a 6.3V 10mm
bayonet filament bulb which can be replaced by unscrewing the jewel from the front.
HIGH – PREHEAT – LOW Switch.
The VX100 should always be switched on, (mains switch on rear of amplifier), with this front panel
toggle switch in its centre position. The amplifier is now in ‘PREHEAT’ mode with just the valve heaters
and low voltages on. This allows the valves to heat up before they get 100s of volts up them, (it’s less of
a shock). After around 60 seconds, the amp can be switch to either HIGH, (around 100 Watts rms) or
LOW, (around 30 Watts rms). Due to recent EU regulations on the use of ‘Standby’ functions and their
associated low-power requirements, we have replaced the function with PREHEAT to avoid any legal
confusion. There will be no difference in operation of the amplifier. When switching the amplifier ON or
OFF please ensure the Volumes are turned down and you leave at least 30 seconds before switching
from PREHEAT to Off. This will ensure extended valve life and avoid any power-down noise. This is
especially relevant if you’re running through a large PA system as any small pop may become amplified
to audience death levels, which may limit your music career.
