zZounds Gear Experts Say...
Create your dream tones with the Positive Grid Reactor 100! This AI-powered combo amp uses prompts, images, and audio to make your ideal tones a reality.

Your Imagination Deserves an Amplifier:
REACTOR is a guitar amp built around creation, not presets. 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 Intelligence-powered tone generation and visual signal chain editing.

REACTOR Control (optional): A footswitch with six switches and expression support. Go wireless or wired, read more stay focused on your performance

Tone that Reacts to You:
Amp Intelligence changes the game by letting you shape tone in powerful 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.

Instant Control:
One knob puts six amp categories at your fingertips. Classic Gain, EQ, and Master controls let you shape tone instantly from the panel. Six essential effects with dedicated buttons and onboard controls for instant tweaking.

Tap into two switches you won't find on any other amp. Push/Smooth takes you from laid-back rhythm to cutting lead without touching distortion. Heat +/- adjusts feel and harmonics without significantly changing volume.

Stage Tone At Any Volume:
Most amps thin out when you turn them down. REACTOR doesn't. Selectable wattage -- 1W, 25W, or full power -- keeps the tone full and present at any volume. A custom 12" speaker in a wood cabinet delivers the warmth and presence you'd expect at stage volume, even in your bedroom. REACTOR sounds like itself wherever you play it.

Describe What You Want. REACTOR Delivers It:
Powered by Amp Intelligence, Creator Hub's Tone Capture gives you three ways to build tone -- using text prompts, images and audio. Start with your go-to favorites, or build something entirely new.

Audio to Tone: Upload a track or record a sound. Amp Intelligence analyzes the source and builds a guitar tone to match, so the tone you hear in the recording is ready to play in seconds.

Image to Tone: See an amp, a pedalboard, or a setup you want to try? Snap it. Amp Intelligence turns any photo into a matching tone.

Text to Tone:Describe an amp, an artist, or a sound in your own words. Amp Intelligence figures out the signal chain and makes it playable.

Build Your Own Amps: Go further than matching existing gear. Combine characteristics, shape deep parameters, and create original amp voices that are entirely your own. Name them, save them, and share them on ToneCloud.

Tone Memory: REACTOR remembers your prompts, inputs, adjustments, and settings. Every time you create, it starts closer to where you want to be.

Where Tone Gets Created. Deep Control, Instant Changes:

Amps: 24 amp models to start. Build as many of your own as you want. Full parameter access to adjust gain structure, EQ, bias, and voicing on any of them.

Effects: Run eight simultaneous effect slots with full parameter control across Gate, Compressor, Drive, Modulation, Delay, Reverb, Wah and EQ. Insert the FX loop anywhere in the signal chain.

Presets: Save unlimited presets by song, session, or genre in the app. Load and access 8 onboard preset slots for instant recall directly from the amp panel.

ToneCloud: Browse and download tones and custom amps from other players, then share your own with the community.
