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.
This tonal updating is due to an all-new preamp mated with our time-honored 2xEL84 25 watt power section
based on our originally-patented Dyna-Watt™ power. This little dynamo delivers its own blend of Badlander with
aggressive attack and percussive midrange while tucking up the low end in a definitive way that is addictive in
both sound and feel. And best of all, this model gives you all the Badlander’s stunning performance in a pack-
age that is lightweight and compact as well as more clip-able than its higher power siblings for times when
power section character and/or overdrive is the call.
While cut from much the same cloth as its forbearer, the original Dual Rectifier Solo Head from the early 90s,
this model stakes new ground and pays homage to rock and heavy sounds in its own new distinctive and more
percussive way.
Up front, the two identical footswitchable preamp Channels offer the ability to configure the amplifier for virtu-
ally any style, making it a supremely versatile choice while decidedly leaning toward all things rock. CLEAN,
CRUNCH, and CRUSH Modes double up and appear in both Channels, allowing for multiple ways to get your
gain signatures done – be they similar or differing - for your two footswitchable sounds.
