MASTER:
This control is the master feed from the end of the pre-amp to the driver stage and the Effects Loop. As you can
see each Channel is fitted with its own MASTER control, enabling both channels relative volumes to be matched regardless of their
extremely different sound styles and gain signatures. The MASTER control makes possible a wide range of sounds
through its ability to use very low Gain sounds at high volumes and conversely, high Gain sounds at low volumes
and everywhere between.
Again, we suggest using the MASTER control in its sensible ranges (9:00 - 2:00). Here, the channels will be easier
to match with each other and the Effects Loop will see more reasonable signal levels.
NOTE: Because the MASTER control creates the send to the Effects Loop, extreme settings will cause a large
signal to be sent to the Loop for that Channel. Not only may this cause possible overloading of the processors Input stage, but will
make balancing both channel’s Effect Send level difficult.
EQUALIZER SECTION:
This section of the Express Plus offers two additional ways to further shape your sound beyond
what the standard array of rotary Tone Controls can do. The choices are either the classic Boogie 5 Band Graphic EQ or our PRESET
DEPTH Control - which uses the same EQ circuitry to create a dial-able EQ version on one control that is pre-shaped to the iconic
mid-dipped “V” slider setting. These choices are channel specific so that you can use either SLIDERS or PRESET for each Chan-
nel. Once you’ve chosen which option you want to use for each Channel, they can be auto-engaged when the Channel is selected,
brought in and out via the Footswitch or Bypassed altogether.
Here are the switches, controls and the functions they perform to control the EQ section.
EQ CONTROL: Toggle
These two stacked 3-position mini-toggles to the Left of the SLIDERS (one for each Channel) in the
EQ Window selects if and how you wish to engage the EQ Section – EQ ON, OFF or FT SW. Between the two mini-toggles in the
centerline between the Channels, is an Orange LED that indicates when the EQ SLIDERS are engaged. When this
light is illuminated, the EQ circuit is Active and you may use the SLIDERS to shape your sound (to use the PRESET
Control, select PRESET with the EQ Style switch to the Right of the SLIDERS).
The Middle position of each switch (O) Bypasses the EQ section altogether and both SLIDERS and PRESET will
not have any effect on the signal.
The Upper position of each switch (EQ ON) engages the EQ section in that Channel. Whatever is selected on the
EQ STYLE mini- toggle (to the right of the SLIDERS) will determine the type of interface that is active in that Channel… SLIDERS
or PRESET.
The Lower position of each switch (FT SW) allows you to engage the EQ section from the Express Plus Footswitch. The Footswitch
EQ button may not turn the EQ on or off if the EQ Control switch is set to either EQ ON or O (switch up or switch middle) as these
positions override the Footswitch EQ button.
