(one sound) and modern high gain, footswitching (multi sound) amplifiers. The HEARTBREAKER assembles all these early innovations (along with many more recent ones) and showcases them in a 2 channel, 5 mode footswitching package that pays ultimate tribute to the soulful voice of these vintage Mark I Boogies. Enough history for now...we thought you might find your new HEARTBREAKERS’... - Page 6 Boogies. There are two ways to access the different channels of the HEARTBREAKER, either via the channel select footswitch (included) - when it is connected to the front panel footswitch jack, or manually by using the front panel channel select toggle switch. You will notice a vertical row of three mini toggle switches that divide the two channels near the center of the front panel.
- Page 7 When reaching from the front of the unit for these controls, the PRESENCE is located on top (nearest to the top of the cabinet) and the REVERB control for that same channel is directly below it. When viewing the HEARTBREAKER from the front, the REVERB and PRESENCE controls for Channel 1 (LOVE) are to the left (closest to the INPUT jack) and the two controls for Channel 2 (LUST) are to the right (closest to the power ON/OFF switch.)
- Page 8 The HEARTBREAKER is fitted with a SLAVE jack and LEVEL control located on the right side of the rear panel (when viewing the unit from the rear). This feature allows you to capture the sound of both the pre-amp and power section when using the unit in a multiple amp rig where external signal processors are fed from several amp sources and then sent to a common power amplifier and set of speakers.
- Page 9 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.

MODE SELECT: CH2 - GAIN: This two position toggle selects the gain structure of Channel 2. The two choices are “LO” and “HI”. NOTE: Channel 1’s (LOVE) “HI” - BOOST mode is much higher gain than any of the other 5 modes in the HEARTBREAKER. -

60 HZ. 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;... -
Page 13: Power Cord Receptacle
(Continued) POWER CORD RECEPTACLE: The total power consumption for the HEARTBREAKER is 3 Amps @ 117 Volts. Thus, a 15 Amp circuit (which is what most house circuitry is wired with) is adequate. Make sure the Euro style A.C. power cord is firmly seated in the POWER RECEPTACLE before powering up the unit. -
Page 14: Rectifier Select
RECTIFIER SELECT: (Continued) NOTE: The stock 5AR4 Rectifier tube is best suited for most applications. If you intend to use your HEARTBREAKER in the 60 watt power position only, or if a 5AR4 should ever fail and you prefer the tone of the tube rectifier to the silicone diodes - it is possible to run the HEARTBREAKER with a 5U4G Rectifier tube. -
Page 15: Presence Control
REVERB CONTROLS: As illustrated below, the HEARTBREAKERS’ REVERB controls are positioned just below the PRES- ENCE controls and if viewing the HEARTBREAKER from the front, the REVERB control for Channel 1 (LOVE) is to the right and closest to the POWER switch with Channel 2’s REVERB just to the left. Each channel has its own dedicated REVERB control and they are totally independent of each other. -

(Continued) SLAVE: This works great for using the HEARTBREAKER as a master send to a processor or when additional power amps are needed for additional power. Some players use this patch point to derive an FX send signal and go to other amps for their wet sound, leaving the HEARTBREAKER dry for definition. - Page 17 CHANNEL 1 - LOVE Presence Tube Rectifier This control is located on rear panel Full or Tweed Power Bubbling Vintage Clean CH 1 LOVE INPUT CH 1 GAIN SWITCH HI MODE HI MODE NORMAL BOOST!

- Page 20 To confirm a noisy power tube, merely put the HEARTBREAKER on STANDBY, remove it from its socket and turn it back on. It will cause no damage to run the HEARTBREAKER briefly with one power tube missing. You may notice a slight background hum, however, as the push-pull becomes unbalanced.

Page 21: Tube Task Chart
DIAGNOSING PRE-AMP TUBE PROBLEMS: Because your amplifier is an all tube design, it is quite possible that you will at some point experience minor pre-amp tube noise. Rest assured - this is no cause for alarm and you can take care of the problem yourself in a matter of minutes by simply swapping tubes. Let us begin by saying;... - Page 22 BIAS ADJUSTMENT: (Part of a continuing series) NOTE: An article written by Randall Smith that BEAM- CONFINING we thought you might find interesting.
