Page 6: Overview
Operating Instructions OVERVIEW Congratulations on your choice of the Rectifier® Badlander™ 25, and Welcome to the MESA/Boogie Family! The amplifier you have chosen represents decades of research and refinement, and we sincerely hope it will bring your playing and your music to new levels of inspiration and enjoyment! The Badlander is the latest in a long line of iconic Rectifier products that carry the tradition of high performance, high gain forward with tighter low end, a more aggressive midrange character, and enhanced harmonic content.
Page 7 Also included in each Channel is our patented Multi-Watt™ power switch rounding out the Front Panel options with power choices of FULL at 25 watts and HALF power at 10 Watts. These power options, with their specific headroom thresholds and characteristics, add versatility and color to the preamp’s many choices, resulting in sounds that are as authentic as they are inspiring to play ...
Page 8: Instant Gratification
INSTANT GRATIFICATION Here below is an “instant gratification” tour of the Badlander’s two channels using the top channel set to CRUNCH for a heavy rhythm sound and the bottom channel set to CRUSH for a high gain soloing tone. This is just one of the countless possible configurations you could use to dedicate the channels to different stylistic roles and tasks.

• The MID control carries a fair amount of top end along with the previously mentioned punch, albeit in a lower place than that of the TREBLE. Keep in mind it can also be used to bring in attack and openness of a different character than that found in the TREBLE.
Page 10: Channel Select
CHANNEL SELECT This switch in the center of the stacked switches allows manual selection of the Channels when the Footswitch is not plugged in or available. The Center position labeled FTSW accommodates the Footswitch when plugged in to the adjacent FTSW jack and allows remote switching between the Channels via the Footswitch. Make sure the switch is in the Center position when using the Footswitch.

of the authentic ingredient to a sound, like blues sounds or classic rock sounds in the Clean Channel cranked. However, you will find the best overall tracking and dynamic response for most styles in the middle range (10:00 - 1:30) of the MASTER controls/overall power output. By all means, when possible, turn the amp up enough to get the power tubes working and doing their magic, adding fullness and color, but more than that isn’t always better.

leaving big low end and open, soaring top end, the strings can feel more forgiving, bouncy, more elastic, and easier to play. Conversely, at higher settings of the MID, where this frequency creates a bump and lows and highs are somewhat overshadowed by midrange frequencies, the sound becomes more forward, and the response can feel to some players less forgiving and even stiff to play.

more dominant, and that compression gives way to “cut,” and dynamic peaks jump out with startling speed and accuracy, unleashing the Badlander’s wilder side. Clean sounds in Channel 1 can generally benefit from slightly higher settings (10:30 – 12:30) than sounds that have overdrive involved in their makeup.
Page 14: Multi-Watt™ Power
Some purists like to run the MASTER all the way up and raise the GAIN until they reach their desired sound–the thinking there being that this achieves the “purest” sound. The belief is this resembles removing the control altogether from the signal path, and in a way it does. However, most all the “vintage non-master” amplifiers have discrete resistors in that place in the circuit anyway to adjust or “tune”...
Page 15: Cold Start Procedure
cluded power cable is connected securely to the IEC Socket on the Rear Panel and the male 3-terminal plug connected to a Grounded 3-Leg AC Wall Socket supplying proper voltage. US Domestic @ 117-120 Volts AC. NOTE: WARNING! Never alter your Power Cable in any way! Doing so will void your warranty and put you at risk of electric shock.

4x12 cabinets may be 4, 8, or 16 Ohms. If you are not sure of the impedance of your cabinet, you may need to remove the Rear Panel in order to verify the impedance rating of the individual speakers. MESA/Boogie 4x12 and 4x10 cabinets come wired to 8 Ohms standard and are wired in series-parallel.
Page 17: Cabclone Ir Direct Interface Section
NOTE: Normally, this is the spot we’d be reminding you to ALWAYS keep a Load connected to your amplifier. However, your Badlander is wired such that when you disconnect the (Speaker) Cable from one or more of the SPEAKER output jacks, the Internal Reactive Load is automatically connected. This means your amplifier is always protected from a no-load condition.

CabClone IR and IR+ units. These were captured using Dynamic and Ribbon microphones and are brighter and more open sounding. MANIPULATING/STORING IR FILES As mentioned in the Overview, the Badlander, the first ever to include our CabClone IR DI, opens up a new world of flexibility and convenience.

or Interface, as well as the LEVEL on the CabClone IR section of your Badlander, BEFORE connecting the cable to the DIRECT OUT. This routine will help avoid unwanted (hot) signals accidentally sent during hook up from damaging your ears and those of others, monitor speakers, etc. GND/LIFT A mini toggle Ground switch is provided, which can lift the circuit Ground from the chassis Ground.
Page 20: Effects Loop
EFFECTS LOOP These two 1⁄4” jacks provide the interfacing patch points for your “rear end” processing needs. The Effects Loop is basically a circuit bridge from the end of the preamp to the Driver stage, with the SEND interrupting the signal at the preamp’s end and the RETURN feeding the power section just before the Driver tube.

Page 24: Diagnosing Pre-Amp Tube Problems
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.
Page 25 Pre-amp tubes don’t normally wear out as a rule. Therefore, it is not a good idea to change them just for the sake of changing them. If there isn’t a problem - don’t fix it. If there is no result from your substitutions, it may be possible that you have more than one problematic tube.
Page 26 MESA/Boogie amplifiers can handle 4 and 8 ohms effectively. Never run below 4 ohms in a tube amplifier unless you are absolutely certain that the system can handle it properly; this can cause damage to the output transformer.
Page 27 SERIES When you wire ( hook-up ) speakers in series, the speakers resistance ( as measured in ohms ) is additive - i.e. putting two 8 ohm speakers in series results in a 16 ohm load. NEGATIVE = POSITIVE = Speaker A = 8 Ohms Speaker B = 8 Ohms SERIES:...
Page 28 COMBINATION OF SERIES & PARALLEL This is really just two sets of series wired speakers connected in Parallel. This is how you maintain a consistent load with multiple speakers. The importance of this is more evident when you have more than one cabinet to connect to your amplifier.
