The Sonnet Series: Amplification Designed to Respect Acoustics

The Sonnet series was designed with a simple idea: to amplify the natural response of an acoustic instrument as faithfully as possible, without "twisting" or coloring it. The goal is to preserve playing nuances (attack, dynamics, harmonic detail) while increasing volume and projection, whether solo, duo, or in a fuller band.

With its 2-channel architecture and features tailored to musicians' real needs (D.I., USB, feedback suppression, Bluetooth), the Sonnet 120 stands as a versatile solution for those seeking a powerful, practical, and quick-to-adjust acoustic amplifier.

For Which Musicians and Usage Contexts?

The Sonnet 120 is aimed at acoustic guitarists (folk, fingerstyle, pop, variety, acoustic jazz) looking for an amp that stays clean at high volumes while retaining the finesse of a quality preamp. Its power reserve makes it suitable for stage, rehearsals, reverberant venues (cafés, small halls), and situations where you need to hear yourself without forcing your playing.

Thanks to the microphone channel with 48V phantom power, it is also well suited for singer-songwriters: you can manage voice and instrument from the same combo, with separate settings and studio-quality reverb. Bluetooth audio playback and the MP3/Line In input also make it an effective tool for playing along with backing tracks, working on a set, or hosting a duo performance.

Key Features: Control, Effects, and Stage-Oriented Connectivity

Each channel has its own controls to finely adjust EQ and reverb level according to the source (piezo pickup, internal mic, vocal mic). The high-pass filter helps clean up the low end (handling noise, stage rumble) and gain clarity, while the brightness control allows you to adjust presence and articulation, very useful depending on string type, pick, or room.

For feedback-sensitive environments, the anti-feedback function is a major asset: it secures the sound when increasing volume or standing close to the amp. The effects loop on each channel facilitates integrating your pedals (delay, chorus, external EQ), while maintaining a clean and logical signal path.

On the output and recording side, the XLR D.I. outputs (per channel and for the mix) simplify connection to a mixing console, PA system, or interface. The USB audio output opens the door to simple recording/streaming uses, and Bluetooth audio provides real daily convenience without unnecessary cables. Finally, the built-in tilt foot improves projection towards your ears-a detail that makes all the difference on stage and in rehearsal.

Sound Character

Designed for acoustic amplification, the Sonnet 120 aims for a neutral, precise, and dynamic reproduction: a spacious clean sound, clear attack, and beautiful definition in the high frequencies, without harshness. The combination of an 8-inch speaker and a tweeter helps reproduce transients, string snap, and playing details, while maintaining controlled low-mids.

The high-pass filter and brightness control let you quickly shape the balance: more warmth and stability in a resonant room, or more air and presence to stand out in a mix. The reverb (Hall, Studio, Chamber, Plate) adds credible depth for voice and guitar, with a "studio" rendering that avoids an overwhelming effect. Result: your acoustic guitar sounds louder, clearer, and controlled in all settings.
