Rear Panel; Fuse - Mesa/Boogie Heartbreaker Owner's Manual

FRONT PANEL & CONTROLS:
GENDER SWITCH: (Continued) CURVACEOUS: This setting is the more vintage sounding of the two. It softens, removing any
harshness and rounds out the corners to produce a breathing, warm vibe. The strings become more resilient and an elastic, almost
rubber-band-like feel emerges as the highs become sweet and the lows spread out and fill the room. This setting combined with the

FUSE: This is the A.C.s' (Alternating Current) main FUSE and provides electrical current protection from outside A.C. fluctuations, as
well as power tube failure damage. Should the FUSE blow, replace it with the same rating in a slo-blo type package. The domestic

NOTE: Like tires on a car, spare FUSES are always a measure of good insurance. Your HEARTBREAKER was carefully con-
structed with reliability in mind! Given the proper care and maintenance, it will deliver years of trouble free service. However, any pro
guitarist who is out there gigging will tell you; spare tubes and FUSES are a must for the fabled cord bag.
Tube Rectifier setting (see rear panel section) defines what vintage is all about.

BOLD: This is the choice for power and punch! Dynamics are exaggerated and articulation
increased, bringing the whole sound forward. Along with this change, headroom is also in-
creased and the overall volume is boosted - making BOLD the obvious choice for loud clean
playing. High gain overdrive sounds track tighter and bass response is more focused around
POWER
the notes which is helpful when the gain is maxed out in the "HI" modes for crunching
rhythm grooves.
REST AREA
U.S. version requires a 3 Amp slo-blo FUSE. A power tube short or failure is often the cause of a blown
FUSE...Follow the cold start procedure mentioned in the ON / STANDBY switch section and watch the
four 6L6 power tubes as you turn the STANDBY to the ON position. If a power tube is going bad or is
arcing you will see it! Turn the STANDBY switch to STANDBY immediately and replace the faulty power
tube and the FUSE if necessary. If you see nothing abnormal as you lift the STANDBY, it is possible that
a power tube shorted temporarily and blew the FUSE. If this is the case, it may work again normally. To
be extra safe you may want to replace all four power tubes in the "shotgun" troubleshooting tradition and
save the replaced set as spares.
