Critic Reviews

Blackstar Sonnet 120 Review (acoustic combo amp) - Guitar Chalk

guitarchalk.com

The Blackstar Sonnet 120 delivers a powerful and warm acoustic tone, making it an excellent choice for practice and small gigs. With superb onboard reverb and a user-friendly interface, it stands out in a market with limited acoustic amp options. However, it falls short on effects compared to rivals like the Fishman Loudbox, lacking diversity in onboard features. Still, for those seeking value and quality, the Sonnet 120 is hard to beat, offering significant functionality at a competitive price. Overall, it’s a solid investment, particularly for those prioritizing sound warmth and versatility.
