Transparent amplification retains your instrument’s tone





The guitarists here at Sweetwater have a strong disdain ? as do most acoustic players ? for amplifiers that alter the sound of our instruments. After all, we install high-end piezo systems In our guitars to capture their natural tone. Why would we want to change it? Blackstar understands this. That’s why they designed the Sonnet 120 to be as transparent as possible. It faithfully amplifies the natural response of your acoustic instrument ? it’s just louder. If you’re picky about your acoustic guitar tone, the Sonnet 120 is the perfect acoustic guitar combo amplifier for you. Just ask Jon Gomm ? he relies on the Sonnet to capture his unorthodox arsenal of modern, neo-Michael Hedges playing techniques, and it definitely delivers the goods.





Player-friendly tone-shaping makes dialing in your sound easy





The Blackstar Sonnet 120 makes dialing in your tone easy. Of course, its transparent sound gives you a great starting point. But beyond that, fine-tuned 3-band EQs enable you to tailor the amp to your venue with a minimum of effort, while Shape buttons toggle between a flat response and one with a mid-cut and high/low boost. An optimized highpass filter enhances your instrument’s acoustic resonance, while a Brilliance control injects your piezo with the perfect amount of high-end sparkle. An effective anti-feedback system quashes unwanted squeals while staying out of your way sonically. You also get four built-in reverbs (Hall, Studio, Chamber, and Plate) to add the final bit of polish to your performance.





Robust feature set is perfect for solo performers





If you’re a solo performer, you’ll value the Sonnet 120’s real-world features. Dual inputs ? each with their own separate set of controls ? accommodate both your instrument and your microphone. If you use a condenser mic, you’ll appreciate the onboard 48V phantom power, while pad and polarity reverse functions ensure maximum sound quality in any situation or environment. The Sonnet 120’s flexible outputs enable easy USB recording and XLR DI-ing to front of house. Built-in Bluetooth connectivity makes streaming backing tracks from your smartphone a breeze (there’s also a line input if you’re going old school). You also get dual effects loops for effortless pedalboard integration, and footswitchable reverb and amp mute. The Sonnet 120’s handy tilt-back stand is icing on the cake.
