Mesa/Boogie F-30, F-50, F-100 owner manual Controls, Bass

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 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.

INPUT

GAIN TREBLE MID BASS

Try setting the BASS control to (7:00 ) for clean sounds in the CLEAN Mode and ( 4:00 ) or below when dialing up High Gain overdriven sounds in this Mode. In the Channel 2 / CONTOUR Mode, try setting the BASS somewhere between ( 10:00 through 2:00 ). These settings will depend upon the amount of Gain and Treble that you have dialed up.

REVERB:

Your new F-Seriesamplifier 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 slightly alter the character of the amplifier as the voicing of the Reverb circuit be-

comes more dominant in the mix.

NOTE: Avoid using high setting the REVERB control when High Gain and Treble settings are in use. This reduces the likelihood of annoying microphonic problems occurring.

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

level of the other Modes.

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.

THIRD: The MASTER control is the Record / Phones Send Level control. When using the direct RECORD / PHONES jack found on the Rear Panel to interface di -
