Positive Grid "REACTOR 100w" Intelligent Guitar Amplifier

The REACTOR Smart Guitar Combo Amplifier is a 1x12 combo amp powered by Amp Intelligence™ technology—a sound engine that shapes tones exactly as you imagine them using text prompts, photos, and audio recordings. Create signal chains on demand or design amplifier sounds that exist nowhere else. With 100 watts of power and selectable output levels, it delivers consistent tone at any volume.

AMP INTELLIGENCE™

A new type of sound engine built on the analysis of more than one million sounds and hundreds of amplifier circuit models. You can now create dynamic tones completely from scratch.

TONE CAPTURE

Enter an idea, take a photo, or record a sound. REACTOR creates a complete guitar tone from it in seconds.

RIG-READY

• 100-watt model
• Custom-designed 12" speaker
• Adjustable power output
• Direct recording to any Digital Audio Workstation (DAW)

TONE MEMORY

REACTOR remembers how you build your sounds and gets closer to your ideal tone each time you create.

Amp Intelligence™ has decoded more than 200 amplifier models at the circuit level, including gain stages, transformers, bias points, and harmonic response, capturing the behavioral DNA of some of the most legendary amplifiers ever built. Every tone it generates is based on the real operation of these iconic amplifiers, resulting in sounds that breathe, feel alive, and respond dynamically to every note you play.

INSTANT CONTROL

A single knob provides access to six amplifier categories. Traditional Gain, EQ, and Master controls allow instant tone shaping directly from the front panel. Six essential effects include dedicated knobs and integrated controls for immediate adjustment.

Two unique switches provide additional flexibility:

• Push/Smooth Switch – Move from relaxed rhythm tones to aggressive lead sounds without changing distortion settings.
• Heat +/- Switch – Adjust playing feel and harmonic character without significantly affecting volume.

Unlike many amplifiers that lose impact at lower volumes, REACTOR maintains its character thanks to selectable power settings (1W, 25W, or full power). Its custom 12-inch speaker and wooden cabinet provide stage-level warmth and presence, even at bedroom volumes.

CREATE SOUNDS YOUR WAY

With Amp Intelligence™, the Tone Capture feature in Creator Hub allows you to build sounds using:

• Text prompts
• Images
• Audio files

Start from your favorite tones or create something entirely original.

Rather than simply recreating existing sounds, you can combine characteristics, fine-tune parameters, and build completely new amplifier voices. Name them, save them, and share them on ToneCloud®.
