Positive Grid - REACTOR 50W Guitar Amp

Your imagination deserves an amplifier.

REACTOR is a new kind of guitar amp built around creation, not presets. Available in 50W and 100W models, it delivers powerful, responsive tone that feels right at any volume — at home, in the studio, or on stage — through a custom 12" guitar speaker and selectable wattage. Powered by Amp Intelligence™, REACTOR turns your ideas—text, images, or audio—into complete, playable tone in real time. You can even design your own custom amps. REACTOR remembers what you like over time — so it grows with you the more you use it.

Powered by intelligence, built with classic amp thinking.

REACTOR is solid, purposeful, and ready for the stage. Every material, control, and connection is there to serve the player, not the spec sheet. From the sturdy wood cabinet to the 1x12 speaker and robust controls, this is a guitar amp first—designed to deliver feel, response, and clarity where it matters most.

Three ways to control your sound

Top Panel – Everything you need is right where you expect it. Classic knobs give you immediate access to gain, EQ, reverb, effects, master volume, and preset recall. Mod switches let you tweak in new, unique ways. Go even further with easy amp and effects selection. No menus. No learning curve. Adjust on the fly and stay in the moment.
REACTOR App – A drag-and-drop tone studio with Amp IntelligenceTM-powered tone generation and visual signal chain editing.
REACTOR Control (optional) – A footswitch with six switches and expression support. Go wireless or wired, stay focused on your performance.

Tone that Reacts to You

Amp IntelligenceTM changes the game by letting you shape tone in new ways. Describe what you want—“tight, mid-gain British crunch”—and REACTOR builds it. Drop in a sound sample, take a photo, or use the Tone Assistant to refine your tone with natural, simple language.

REACTOR works in these powerful ways:

● Text, Audio and Picture to Tone: Type your tone idea. Grab an image. Upload audio. REACTOR generates a tone, whether it’s matching your favorite artist, piece of gear, or dreaming up something creative.
● Build amps: Now you can build the amp itself. Your input can recreate familiar gear—or build amps that have never existed in the physical world. Save, share.
● Conversational Tweaks: Tell it what you need—"more warmth," "less gain," "add some space." REACTOR responds.

Feels Like an Amp. Reacts Like Nothing Else.
REACTOR's Amp Intelligence decoded over 200 amp designs at the circuit level — gain stages, transformers, bias points, harmonic response — capturing the behavioral DNA of the most legendary amps ever built. So every tone it builds is grounded in how great amps actually work. The result is tone that breathes — dynamic, alive, and responsive to every note you play. Any tone you can imagine delivered on demand.
