Full-Range 1x15" Tone

At its core is a premium Sica NEO 15" speaker, complemented by an Eminence tweeter for enhanced high-frequency detail. Together, they deliver rich low-end authority, smooth midrange character, and crisp, well-defined highs that sit perfectly in any mix.

Built for Real-Wold Versatility

An FX Loop ensures seamless pedal integration, while the Balanced DI Output provides a reliable signal for live or studio use. Integrated Tweeter and Speaker Mute switches give players additional control over their output, whether shaping top-end response or muting the speaker for silent operation.
