FROM MESA ENGINEERING:

Delivering a sonic and weight profile that’s a bit more trim, the Rectifier® Badlander™ 50 holds its own while adding a distinct tonal character to the Badlander Series. Even more aggressive sounding, yet with an inviting, effortless feel, it’s buffed and ready to go places where less output power is the call.

Here in the Badlander 50, the 2-Channei preamp hooks up with two different and perfect power displacements that enhance everything from clean to clipped to wildly saturated. The 50 Watt setting delivers bold authority and the highest headroom while the 20-watt setting finds the power tubes re-wired for Triode operation that unveils greater clipping potential and a mid-scooped, harmonic-laden response that reveals trademark EL34 Tone.
