Channel Select; Reverb 0/Fs - Mesa/Boogie MARK VII Owner's Manual

The three stacked Reverb Mix controls reside in the Graphic EQ Window just to the left of the EQ Sliders. These
mini pots control the Reverb mix in each Channel, with Channel 1 at the top, Channel 2 in the middle position,
and Channel 3 at the bottom of the stack. Once the Reverb has been turned on with the Reverb mini toggle men-
tioned above, simply turn the Reverb controls up until you reach the desired mix level in each of the Channels.
The Reverb may also be stored under MIDI Program Change commands and can be triggered on or turned off
automatically with one tap of a MIDI foot controller's buttons or other standard MIDI controller switch. See the
section in this manual under MIDI for more pertinent information regarding controlling the Reverb with MIDI.
Because the MARK VII houses so many sounds, gain ranges, and dynamic characteristics within its 3 Chan-
nels and 7 Modes, it is not always possible to have uniform reverb mix levels available across the breadth of
its sonic playbook.
The Modes in Channels 1 and 2 range from the more traditional gain circuits like CLEAN and FAT to the high
gain signatures found in CRUNCH and MARK VII. With both the gain and dynamic content differences being
this variable and wide-ranging, it is nearly impossible to achieve uniform input-send and return-mix levels in the
reverb circuitry. Therefore, in the cleaner, lower gain Modes like CLEAN and FAT, you will experience greater
reverb depth, while in the CRUNCH and MARK VII Modes, the depth (overall reverb available) is reduced.
Fortunately, this difference in mix/level due to gain characteristics also tracks the musical styles that tend to
be played in the Modes. In CLEAN and FAT, where clean sounds are favored, be they rhythmic chording or
single note soloing, you will find plenty of reverb depth to play virtually any style from R&B to jazz, country to
surf music. In the CRUNCH and MARK VII Modes, where gain rules supreme and Crunch Rhythm and burning
soloing are the main applications, high reverb mix settings are usually not called for or even appropriate. That
said, you will likely find ample reverb depth available for most of your needs. Again, these mix level differences
are a result of widely ranging gain signatures and the challenges they present to the reverb circuit.
In Channel 3, due to a similar gain structure across the 3 Modes, a little more consistent reverb mix level is pos-
sible throughout. There is not quite as much reverb depth available as in the CLEAN and FAT Modes in Chan-
nels 1 and 2, but there is a little more available than in the CRUNCH and MARK VII Modes in those Channels.
Regardless of how you choose to apply the lush tube Reverb throughout your Channels and Mode choices, the
MARK VII's Reverb will likely prove to be a valued part of many sounds, be they more traditional clean-based,
or high gain and saturated in nature.

CHANNEL SELECT

Again, this 3-position mini-toggle located in the upper right-hand corner of the Graphic EQ window allows for
the selection of the Channels when the Footswitch is not in use or unavailable. It also allows for the selection
of the Channels before storing them under MIDI Programs. (See the MIDI section of this Manual for program-
ming/storing instructions.)
As notated with Panel Art, the upper position brings up Channel 1, and the middle position calls up Channel 2
and is where the switch needs to be set for the MESA Footswitch to function. Channel 3 is activated when the
mini toggle is in the lower position.
FX 0/FS
This 2-position toggle located in the Center of the 3 stacked switches in the Graphic EQ window engages/
controls the Effects Loop. When the switch is set to the upper position, the Effects Loop is activated and in
the signal path. When the switch is in the lower/down position, the loop is Off but can be switched On and Off
via the FX button on the MESA Footswitch. The adjacent FX ON LED will illuminate when the Effects Loop is
switched On and in the signal path.

REVERB 0/FS

As mentioned above, this 2-position toggle located at the bottom of the 3 stacked switches on the right-hand
side of the Graphic EQ window engages the Reverb circuit. When the switch is set to the upper REV position,
