Overview
Congratulations on your choice of the ROSETTE™ DI-PREAMP and welcome to the MESA/Boogie® family! First, we would like to
thank you for choosing us as your amplifier company and trusting us to help create your musical voice. This is something we never
take for granted and you’ll find that we are here and ready to assist you should you ever need help. Our goal is to help you sound your
best at all times! We feel confident that your new pre-amplifier will bring you many years of reliable service, rewarding inspiration and
create for you a newfound freedom to express your music. You have chosen an instrument bred of a fine heritage and this model is
yet another testament to our legacy of Tone.
Our goal with the Rosette Series was clear from the start and our commitment to excellence has guided us to what we feel is the
FIRST ACCURATE Acoustic DI Preamp/Pedal and, the Rosette 300 Watt 2x8 Combo Amplifier.
In Rosette, we opted for architecture straight from high-end recording console designs. We developed Input stages that were not the
typical, compromised dual-purpose circuits fed by universal XLR+1/4” combo jacks found on many acoustic amplifiers in the mar-
ketplace. Instead, we chose dedicated, time-tested designs, proven over decades of great recordings, to deliver the uncompromised,
accurate truth.
This dedicated acoustic instrument Preamp and DI platform was initially designed for acoustic guitars, but it is also a great choice
for mandolin, ukulele, violin/fiddle, dulcimer, cello, upright bass and other varied acoustic instruments. Not only does The Rosette DI
Preamp include a rich feature set suitable for the professional gigging player, but it also includes touring-grade, Line Level Balanced
Preamp Output and a studio-quality Mic Level Balanced DIRECT Output.
The ROSETTE DI Preamp and 2x8 Combo represent the new frontier in the MESA/Boogie’s amplifier bloodline. This tone-infused
powerhouse pedal is both compact and light-weight, yet built to go the distance with the features and control necessary to continue
the legacy that was started almost 50 years ago in that shack in the redwoods above Lagunitas, California. All MESA amplifiers and
products, like Rosette, are handcrafted in Petaluma, California using the Finest Materials from Around the World.
