Positive Grid Spark Reactor 50: Next-Level Intelligence Amp Combo for Limitless Tone Creation

The Positive Grid Spark Reactor 50 is a seriously clever 1×12” combo amplifier that takes amp modeling into a whole new era. Powered by its groundbreaking Amp Intelligence sound engine, it doesn’t just emulate classic amplifiers—it literally builds tones exactly the way you imagine them. Whether you want to recreate a sound from a quick text description, a photograph of a rig, or an audio recording, you can build full signal chains on the fly or dream up completely original amp designs that do not exist anywhere else. With selectable wattage onboard, you can easily dial in your perfect tone and retain that authentic responsive feel at quiet bedroom volumes or crank it up for rehearsals and gigs. Best of all, the Reactor actually learns your tonal preferences over time, meaning this intelligent amplifier grows and evolves with you the more you use it.

• AI-Powered Creator Hub: Features Tone Capture technology in the Reactor app that builds playable custom tones in three ways: Audio to Tone (analyzing uploaded tracks), Image to Tone (turning photos of gear into signal chains), and Text to Tone (generating patches via simple natural language descriptions).

It comes packed with modern essential connectivity, including USB-C audio recording, Bluetooth audio, Line Out with cabinet simulation, MIDI, power amp input, built-in tuner, and Wi-Fi for over-the-air updates.
