Blackstar Sonnet 120, 120-Watt Acoustic Amp, Blonde

The Blackstar Sonnet 120 Blonde is a stage-ready acoustic amp that combines raw power, pristine clarity, and tasteful boutique styling into a single, elegant combo. With a full 120 watts of headroom, this amp is tailor-made for serious acoustic performers—whether you're gigging in mid-size venues, playing outdoor sessions, or simply want your instrument’s tone to breathe with studio-like definition at any volume.

Finished in a vintage blonde tolex with a classic oxblood grille, the Sonnet 120 doesn’t just sound refined—it looks the part too. But beneath that classy exterior is a professional-grade sound system featuring a custom-designed 8” speaker and a high-frequency tweeter, delivering a wide, flat response that preserves every subtle nuance of your playing—from warm lows and detailed mids to the shimmer of harmonics and percussive strums.

The dual-channel design gives you dedicated inputs for guitar and microphone, each with its own 3-band EQ, phase control (to combat feedback), and studio-quality reverb selection (choose from Hall, Room, Plate, and Spring). You can sculpt a polished, balanced sound with total control, whether you’re performing solo or blending guitar and vocals.

It also comes loaded with modern convenience features: Bluetooth audio streaming, a USB audio output for direct recording, XLR DI out for going straight to the PA, and a tilt-back stand built right into the cabinet for ideal stage monitoring. The Sonnet 120 manages to be incredibly powerful without compromising the natural voice of your acoustic instrument—making it a favourite for both singer-songwriters and acoustic purists.

Musicmaker staff love this powerhouse in its beautiful blonde finish—perfect for players who want bold acoustic projection wrapped in boutique visual charm.
