POSITIVE GRID - REACTOR 100 - SMART GUITAR AMP - 100 watts

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 design amplifiers that do not exist anywhere else. 50W or 100W with selectable power for consistent tone at all volumes.


Amp Intelligence:

A new type of engine with 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:

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


Gig Ready:

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


Tone Memory:

REACTOR remembers how you build your tone and gets closer each time to your signature sound.

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


How REACTOR creates tone:

The REACTOR 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 the real behavior of great amplifiers. 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 analyzed
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 panel. Six essential effects with dedicated knobs and built-in controls allow immediate adjustments.

Access two switches you will not find on any other amplifier. Push/Smooth takes you from laid-back rhythm to cutting lead without touching distortion. Heat +/- adjusts feel and harmonics without significantly changing volume.


Stage Sound at Any Volume:

Most amplifiers lose body when the volume is lowered. REACTOR does not. Selectable power — 1W, 25W, or full power — keeps a full and present tone at every level. A custom 12" speaker in a wooden cabinet delivers the warmth and presence expected on stage, even in your bedroom. REACTOR maintains 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 — via text, images, or audio. Start with your favorites or create something entirely new.

See an amplifier, pedalboard, or setup you want 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 your desired result.


REACTOR APP
Where tone comes to life.


Amps:

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


Effects:

Use eight simultaneous effect slots with full parameter control for Gate, Compressor, Drive, Modulation, Delay, Reverb, Wah, and EQ. Insert the FX loop at any point in the signal chain.


Presets:

Save unlimited presets per song, session, or genre in the app. Load and access 8 onboard presets for instant recall directly from the amp 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 in the signal chain and integrate external pedals via the FX loop anywhere in the routing. Every change is immediate and audible.
