Mesa/Boogie DC3 manual Treble, Midrange, Purpose MID Control From 0 to about, Bass

GAIN: (Continued)

probably a good time to mention that most of the great sounds can be found by setting the GAIN Control moderately, especially in the LEAD Channel. For example, somewhere between 2 thru 6 In the RHYTHM Channel try setting this control somewhere between 3 thru 8 . Use of moderation here will reduce the likelihood of pesky tube microphonic problems ever occuring, while at the same time making the two channels easier to balance in relative listening volume and effects send signal strength.

TREBLE:

As with most guitar amplifiers, the TREBLE Control is the strongest of the three rotary tone controls. It controls the blend of high frequencies in a wide band between the midrange and presence frequency ranges. Its setting on the DC-3also determines the blend and strength of the MIDDLE and BASS Controls. Set high, it is the dominant control, minimizing

comes the recessive control and a warmer, darker blend is produced. Dial with care. Subtle tweaking of this control tends to produce the best results.

MIDRANGE

Your new Dual Caliber uses a unique Midrange Circuit that not only blends in rich warm midrange, but goes beyond to give you an added bonus. Through endless daily tone dreaming, the “if-only” design dictum led to the dial-in-gain boost. In the DC-3a third over the top crunch sound was made possible by the inclusion of the RHYTHM Channels dual

this still isn’t crazy enough for you...Max the GAIN and TREBLE Controls and set the PRESENCE Control to 0 or 1 , turn on the Graphic and give it the old “V” curve and plug into a 4x12 with some Celestion Vintage 30’s or 25’s. This should be sufficently heinous for even the sickest crunch fiends. As you can see, the versatility that this dual purpose MID Control lends to the Rhythm Channel greatly expands its usefulness as both a clean and overdrive channel.

NOTE: The lower region of the MID Control determines midrange punch and boldness in lower gain sounds and a smooth vocal blend in high gain sounds. It can be very effective acting as a “cut through the band control” in certain situations. Dial to taste, remembering that the setting of the TREBLE Control greatly effects this controls strength.

BASS:

This control blends in the lower frequencies and its effectiveness, again, depends on the setting of the TREBLE Control. It should be set with moderation as extreme settings in either low or high directions can
