POSITIVE GRID - REACTOR 50 - SMART GUITAR AMP - 50 watts

REACTOR is a 1x12 combo amp powered by Amp Intelligence™ — a sound engine that builds tones the way you imagine them — from prompts, photos, and recordings. Create signal chains on demand or design amplifiers that exist nowhere else. Available in 50W or 100W with selectable power for consistent tone at any volume.


Amp Intelligence:

A new type of engine trained on over 1 million analyzed tones and hundreds of amplifier designs studied at the circuit level. You can now create a dynamic tone from scratch.


Tone Capture:

Type an idea, take a photo, or record a sound. REACTOR builds your complete tone in seconds.


Ready for the gig:

50W and 100W models, custom 12" speaker, selectable power, and direct recording to any DAW.


Tone Memory:

REACTOR remembers how you build your tones and gets closer every time to your personal sonic signature.

Powered by intelligence, designed with the spirit of classic amplifiers.


How REACTOR creates tone:

REACTOR's Amp Intelligence engine has decoded more than 200 amplifier designs at the circuit level — gain stages, transformers, bias points, harmonic response — capturing the sonic DNA of the most legendary amplifiers ever created. Every tone it generates is therefore based on how great amplifiers actually work. The result: a tone that breathes — dynamic, alive, and responsive to every note you play. Every sound you can imagine, available on demand.

200+ Amplifiers decoded
1000+ Circuit parameters learned
1M+ Tones analyzed


Instant Control:

A single knob gives you access to six amplifier categories. Classic Gain, EQ, and Master controls let you shape your tone instantly from the front panel. Six essential effects with dedicated knobs and built-in controls provide immediate adjustments.

Access two switches you won't find on any other amplifier. Push/Smooth takes you from laid-back rhythm tones to aggressive lead sounds without touching the distortion. Heat +/- adjusts feel and harmonics without significantly changing the volume.


Stage Sound at Any Volume:

Most amplifiers lose fullness when the volume is turned down. REACTOR does not. Selectable power — 1W, 25W, or full output — maintains a full, present tone at every level. A custom 12" speaker housed in a wooden cabinet delivers the warmth and presence expected on stage, even in your bedroom. REACTOR keeps its sonic identity wherever you play.

Describe what you want.
REACTOR delivers it — full, rich, and dynamic.

Powered by Amp Intelligence, Tone Capture in Creator Hub gives you three ways to create your sound — through text, images, or audio. Start with your favorites or create something entirely new.

See an amplifier, pedalboard, or setup you'd like to try — or anything that inspires a sound. Take a photo. Amp Intelligence transforms any image into a matching tone.


Create Your Own Amplifiers:

Go beyond reproducing existing gear. Combine characteristics, adjust advanced parameters, and create original amplifier tones that are entirely your own. Name them, save them, and share them on ToneCloud.


Tone Memory:

REACTOR remembers your prompts, inputs, adjustments, and settings. With every creation, you start closer to the result you want.


REACTOR APP
Where tone comes to life.


Amps:

24 amplifier models to get started. Create as many as you want. Full parameter access lets you adjust gain structure, EQ, bias, and the sonic character of each one.


Effects:

Use eight simultaneous effect slots with complete parameter control for 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 presets for instant recall directly from the amplifier panel.


ToneCloud®:

Browse and download custom tones and amplifiers created by other musicians, then share your own with the community.


Signal Path:

Move effects freely within the signal chain and integrate external pedals through the FX loop at any point. Every routing change is immediate and audible.
