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  
Looking to the Rear Panel, features include, first, a full complement of SPEAKER OUTPUTS with two 4 Ohm and 

one 8 Ohm jacks, enabling a wide array of impedance matching options for your favorite cabinets and most 

popular speaker configurations. 
Next, the onboard CabClone™ IR DI Section opens a new world of flexibility and convenience, providing 8 

choices (repeated in each Channel) of Impulse Response Captures of our most popular MESA Speaker Cabinets 

miked for Live applications. This channel-specific ability to assign your cabinet IRs means you can treat clean 

and overdrive sounds differently, applying just the right cabinet style (sealed or open back) and speaker type 

(ceramic or alnico) for optimized performance, live or in the studio, consistently and conveniently. 
These can be used live with the speaker active for a mix of miked and direct feeds or in Silent Mode for stu-

dio applications with the great feel of your amplifier remaining intact. This is possible in part due to the great 

sounding, great feeling built-in reactive Load that allows integration of the power section and all its character 

and dynamic components without the need for a speaker cabinet connected for protection of your output 

transformer and tubes. 
This addition makes the Badlander a mighty riff-catcher as the first MESA amplifier to feature such comprehen-

sive, convenient, and inspiring DI performance. With the Badlander’s vast preamp versatility, power options, 

and the fact you can record or perform “silently” and safely with no live speaker as well as direct mixed with 

your favorite Cab miked up, it sets a new standard for Tone, feel, and convenience in capturing your own brand 

of electrified guitar magic direct.
 The interface points and features of this powerful inclusion appear as follows: a standard 3-Pin XLR for the bal-

anced DI signal, a Circuit-to-Chassis GROUND/LIFT Switch, a standard USB port to interface with your computer 

for File manipulation/transfer/downloads, a HEADPHONE Output, a LEVEL control to adjust the DI Output and 

Headphone level, and a pair of CAB SELECT 8-position Rotary Switches enabling you to call up the different 

Cabinet choices for each preamp Channel. 
The CabClone IR circuitry also supports third-party IRs, and the processor can hold, depending on File size, 

hundreds of IRs in its Storage Library that you can drag into any of the 8 Preset Locations in each Channel 

for a customized set of Cab choices. Simply connect the Badlander to your computer using the USB port and 

manipulate the IR Files in accordance with your needs. 
Next on the Rear Panel the Badlander includes a no-compromise buffered serial EFFECTS LOOP that provides 

a patch point between the preamp and power section for seamless integration of processing you don’t want 

on the amp’s Input. Time-based Effects such as Reverb, Delay, Chorus, Flange, and in some cases, even things 

like compression, are all candidates for use in this Tone-preserving EFFECTS LOOP. 
The Fuse Holder rounds out the Rear Panel. Always use the proper rating for your particular model in a Slo-Blo 

type package. 
Now it’s time to get to the information that will help you get the most enjoyment out of your new amplifier.
