Bass; Reverb; Master; On/Standby & Power On Switches - Mesa/Boogie F-100 Owner's Manual

CONTROLS:
MID: (Continued) pressed, even feel to the strings and therefore less apparent resistance to the pick. As the MID control is increased,
( 11:00 through 11:30 ), the sound is rounded-out and filled-in with a focused mid attack appearing rather quickly. As you would guess,
the feel starts to change - becoming more resistant. Above this region the MID control could be used to compensate for either weaker
pick-ups or for times when a specific deficiency is produced by either an extremely high setting of other tone controls, or a physical
anomaly in the room. While these MID control settings ( 2:00 - 5:00 )can introduce added gain and create enhanced focus, the trade-
off will be a stiffer, more forward, less compressed feel.

BASS:

This control blends in the lower frequencies and its effectiveness, again, depends on the setting of the TREBLE control. It should also
be set with moderation, as extreme settings in either low or high directions can produce an unbalanced tone. In any one of the three

REVERB:

Your new F-Series amplifier is equipped with a rich, natural sounding analog Reverb circuit. The REVERB control enables you to
dial-in just the right amount of Reverb to be mixed with the dry signal. It is normal for extreme settings of the REVERB control to

MASTER

MASTER:
The individual MASTER controls serve three purposes in the layout of the F-Series. FIRST: They serve as level balancing controls
for each of the two channels. This enables a wide range of front end Gain settings to be matched to a given listening level and the

NOTE: Avoid using high setting the REVERB control when High Gain and Treble

SECOND: They act as Effect Send controls for each Mode in the Effects Loop. As with
many of the controls on the F-Series, the best results for balance and tone are usually
found in the medium range of this control.

Modes, be especially careful using higher Gain settings. Too
much Bass will cause a flabby unfocused sound that can't be
dialed out because excessive Bass has been introduced to the
pre-amp in the early stages.
Try setting the BASS control to (7:00 ) for clean sounds in the

Mode, try setting the BASS somewhere between ( 10:00 through

Treble that you have dialed up.
