Positive Grid Reactor 100W: Creative control and advanced modeling

The Positive Grid Reactor 100W is designed for guitarists who value real-time tone shaping and maximum flexibility. At its heart is "Amp Intelligence," an engine that analyzes over 200 classic circuits, letting this amp reproduce the dynamic response and harmonics of vintage tube models. Unique to this model is the ability to generate a signal chain from a prompt, a recording, or even a photograph. Fast access to sound-shaping controls on the top panel minimizes menu-diving and maximizes playing time. This amp proves itself as a reliable tool for practice, recording, rehearsals, and live gigs.

Signature technology: Tone Capture and hardware excellence

What makes the Reactor 100W notable is Tone Capture, enabling users to design sounds by typing a description, uploading a track sample, or snapping a photo. Adjusting the "Push/Smooth" and "Heat" controls changes the presence, attack, and harmonics on the fly. The amp features a custom 12" speaker with a premium magnet for tight, clear projection and robust headroom—essential for clarity at any volume.

Adaptable power and pro connections

Selectable power (100W, 25W, 1W) lets you move from home to stage without losing tone. The advanced connectivity accommodates a variety of setups, supporting direct recording and seamless integration.

• Power Output: 100W / 25W / 1W — practice quietly, record in the studio, or fill a venue with sound while retaining amp character.
• Playing through the 12" (30.5 cm) custom speaker at 8Ω ensures your tone projects crisply for any style.
• USB-C Recording: 24-bit / 48 kHz audio interface — direct connection to macOS or Windows DAWs, no additional hardware necessary.
