Mesa/Boogie Heartbreaker Owner'S Manual Download Page 9

At this point we would like to encourage you to take a break and enjoy your new amplifier for a bit. Give it a good test run and see what
25 years of Tone can sound and feel like. And when you return, beaming from the ride, we’ll be ready to get more specific with the
channels and the individual controls. So ‘till then...Enjoy !

And once again, we appreciate you trusting us with your tone. Thank you for choosing us to be your amplifier company...Welcome to
the 

Mesa/Boogie

 Family !

VOLUME:   Like most amplifiers, the VOLUME (front end gain) control in each channel determines it’s sensitivity and overall tonal
characteristics. It meters the amount of gain that your guitar signal will produce. In the 

HEARTBREAKER

, we paid special attention

to the amount and frequencies of gain present in each mode, making sure the whole range of available gain is
musically usable. We also worked diligently with our suppliers to develop pots with tapers useful to players that
require a touch sensitive relationship of input signal level - to gain saturation...an essential ingredient to a great
amps’ expressive nature. To maximize your musical expression, spend some time learning the different re-
gions of gain in each mode and the tonal colors that they enhance.  Almost more - or certainly equal to the tone
controls, the VOLUME control shapes your sound.

TREBLE:   As with most guitar amplifiers, the TREBLE control is the strongest of the three rotary tone controls. Its setting on the

HEARTBREAKER 

determines the blend and strength of the MIDDLE and BASS controls. Set high, it is the dominant control,

thus minimizing the amount of MID and BASS that would be possible in the mix.

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

MIDDLE:   Your new 

HEARTBREAKER 

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
MIDDLE control. In the 

HEARTBREAKER 

another great pushed sound was made possible by the inclusion of a dual purpose

MID, which is built into Channel 1’s MID control.

From 

 to about 

 the taper is adjusted to act as a very effective MID control. As you

increase the MID to 

 and above, you will hear the lower MIDS getting more pronounced and

fatter. At about 

 the MID leaves behind the old notion of being a tone control and becomes a

truly usable gain control. This upper range is a smokin’ addition to Channel 1’s  VOLUME
control for all kinds of higher gain rhythm sounds. Try the MID set high and the VOLUME
control at about 

 - 

 for a cool blues solo sound.

If this still isn’t crazy enough for you...Max the VOLUME and TREBLE controls and set the
PRESENCE control to 

 - 

 and plug the 

HEARTBREAKER 

into a 4x12 with some

Celestion Vintage 30’s or 25’s. The versatility that this dual purpose MID control lends to Chan-
nel 1’s “LO” gain mode greatly expands its usefulness as both a clean and overdrive channel.
