Mesa/Boogie Heartbreaker Owner's Manual 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 !
FRONT PANEL & CONTROLS:
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-

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.

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
