Positive Grid REACTOR 100 Guitar Amplifier

Intelligent 100-watt 1x12 combo amp with Amp Intelligence, extra headroom and modern connectivity

Overview

The Positive Grid REACTOR 100 Guitar Amplifier is an intelligent 1x12 combo built for players who want more power, punch and projection from Positive Grid’s next-generation amp platform. Powered by Amp Intelligence, REACTOR can create playable guitar tones from text prompts, photos and recordings, turning your ideas into complete amp-and-effects signal chains in seconds. With 100 watts of power, selectable 100W / 25W / 1W operation, a custom-voiced 12 inch speaker with premium magnet, USB-C direct recording, Bluetooth audio, MIDI input, FX loop, headphone output and deep app-based editing, REACTOR 100 is designed for players who need a flexible amp for home, studio, rehearsal and larger performance environments.

Features

REACTOR 100 uses Positive Grid’s Amp Intelligence engine, which is built from circuit-level analysis of over 200 amp designs, more than 1,000 circuit parameters and over 1 million tones. Instead of only scrolling through presets, you can describe the sound you want, use an image as inspiration or capture a tone from audio, and REACTOR builds a complete playable signal chain from that input.

The REACTOR app gives you deep control over the amp’s sound and workflow. It includes 24 factory amp models, 27 effects, full parameter access for gain structure, EQ, bias and voicing, unlimited app-based preset storage and ToneCloud sharing. Each preset can include one amp model, up to eight simultaneous effects and an FX loop placed within the signal chain, making it easy to create song-specific rigs, studio tones or original amp voices.

The REACTOR 100 is the higher-powered model in the lineup, making it especially useful when you want more clean headroom, stronger projection and a punchier response. Selectable 100W, 25W and 1W power modes let the amp stay full and present at different volume levels, while the custom-voiced 12 inch speaker with premium magnet and wood cabinet help deliver a real amp feel whether you are practicing quietly, tracking direct or playing with a band.

Hardware controls keep the amp fast to use without needing the app for every adjustment. The top panel includes amp category selection, Gain, Bass, Mid, Treble, Master, FX level, dedicated effect buttons and Tap, while Push/Smooth and Heat controls let you adjust feel, harmonic response and lead/rhythm character quickly. Rear-panel connectivity includes USB audio for 24-bit / 48 kHz recording, Bluetooth 5.0, line output with cab simulation, headphone output, FX loop, MIDI input, Power Amp input and REACTOR Control input for the optional footswitch.
