INTELLIGENT GUITAR COMBO AMP

REACTOR is a 1x12″ combo amp powered by Amp Intelligence™ — a sound engine that builds tone the way you imagine it — from prompts, photos, and recordings. Create signal chains on demand, or build amps that don't exist anywhere else. 50W or 100W with selectable wattage for consistent tone at any volume.

HIGHLIGHTS

Your imagination deserves an amplifier.

AMP INTELLIGENCE™ A new kind of engine with over 1M tones analyzed and hundreds of amp designs studied at the circuit level. Now you can build dynamic tone from the ground up.

TONE CAPTURE Type an idea, snap a photo, or record a sound. REACTOR builds your complete tone from it in seconds.

RIG-READY 50W and 100W models, custom 12" speaker, selectable wattage, and direct recording to any DAW.

TONE MEMORY REACTOR remembers how you build tone and gets closer to your sound every time.

THE AMP

A new standard.

Powered by intelligence, built with classic amp thinking.

How REACTOR builds sound.

REACTOR's Amp Intelligence™ tone engine 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.

CREATOR HUB

Describe what you want.

REACTOR delivers it — full, rich, and dynamic.

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 — or anything that inspires a sound. 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.

REACTOR APP

Where tone gets created.
