MESA Acoustic


Mesa Rosette 300 / Two:Eight

With the Rosette 300 2x8 Mesa has turned their eyes and ears toward amplifying these sounds, one thing more than any other stood out as an objective; Do No Harm. In its sincerity and perfection, there is no reason to “enhance” the sound of the acoustic guitar, or any other acoustic instrument for that matter, but rather… just reproduce it.

Unlike electric guitar amplifiers that offer a myriad of enhancements and often complete re-voicings, the acoustic instrument has all the complex harmonic content it could ever need, on-board. All that is required is the accurate reproduction of that beauty.
