Product Overview
Capture Your Acoustic’s Tone with Detail and Clarity Like Never Before
The Rosette® 300 Acoustic Combo with 300 Watts of portable power, 2 Channels and a professional grade feature set for home, studio or stage. Few can deny the intrinsic beauty of the Acoustic Instrument, especially the Acoustic Guitar. The visual beauty of the Tonewoods, the curvaceous shapes and elegant lines of body styles, and the delicate artwork of inlay all coalesce in harmonious interplay with tensioned strings to produce musical promise. So when we at MESA® turned our 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 myriad 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. While staying true to the concept of Do No Harm, few products or companies seem to share this perspective for Acoustic Amplification. And when it comes to the electronic and mechanical components and design needed to fulfill that order, it’s easier said than done. It requires a commitment to using the absolute best components and circuit design dedicated to uncompromising accuracy, purity of sound and the lowest possible extraneous noise. The ROSETTE line is a dedicated acoustic instrument platform designed not just for acoustic guitars, but also for mandolin, ukulele, violin/fiddle, dulcimer, cello, upright bass and other uniquely acoustic instruments. 2x8 or 1x10 FORMATS. EACH OFFERING A UNIQUE TONAL CHARACTER! We are proud to offer a choice of speaker configurations for the Rosette 300 Acoustic Amplifier. The detailed accuracy and dimensional width of the Rosette 2 x 8” Combo is now joined by an EQ friendly Rosette 1 x 10” Combo for yet another take on accurate acoustic amplification. The original Rosette Combo trades the finger-style enhancing mid-focus and detail of the 2 x 8” speaker configuration for a warmer, mid-scooped character in the new 1 x 10” Combo that also re-voices the top-end in a pleasing way that compliments flat picking and strumming. The Rosette 1x10’s “mainstream” sonic signature makes it easier to get accurate, inspiring sounds quickly and with less adjustment of the amplifier’s powerful controls and creates a friendly all-around tool in contrast to what some experience with the 2 x 8 Combo as a surgically precise instrument. Both are valid and have their place, each owning a musical niche and reproducing differently yet accurately, a range of sonic tastes and playing styles. Our reverence and appreciation for acoustic instruments guides the designs of the Rosette Series products. Our commitment to produce innovative, reliable and inspiring musical instrument amplification for more than 50 years, finally includes the incredible world of acoustic instruments.
