REACTOR: Amp Intelligence from Positive Grid LLC helps guitarists and bassists create digital replicas of their physical amplifiers and pedals. The app uses machine learning-based Amp Intelligence to profile tube amps, cabinets, and effects, producing shareable tone profiles. A guided capture process, ToneCloud upload/download, and direct sync with Spark 2 compose the main feature set. Players who want portable access to specific vintage amps or consistent studio-ready tones across devices benefit most from this workflow for practice, recording, and live performance.

What is REACTOR used for?

REACTOR concentrates on the capture phase of guitar and bass tone work, turning physical rigs into portable digital profiles that can travel with a player. The app applies Positive Grid's Amp Intelligence to analyze signal behavior so profiles respond to playing dynamics. This approach targets the moment between setup and performance, enabling users to recall a specific tonal identity across rehearsal, studio, and stage situations.

What audio hardware and platforms does it require?

The app runs on Android and requires a compatible audio interface to perform profiling, so hardware connection is part of the workflow. Key compatibility points include:

• Android device plus a compatible audio interface
• Direct sync capability with Positive Grid Spark 2
• ToneCloud upload and download for sharing profiles

How faithful are the captured tones?

Amp Intelligence applies machine learning to model complex tube and pedal behavior, allowing captures of single pedals or entire chains while preserving playing dynamics. Community feedback highlights accurate reproductions, and the guided capture view helps align mic placement and signal routing for consistent results. Captured profiles are usable across Positive Grid platforms so players can audition their tones on compatible hardware before performing or recording.

Is REACTOR better for beginners or experienced players?

The guided capture process lowers the barrier for players new to profiling by showing signal routing and mic-placement steps, making an initial session easier to complete. Ownership of physical amps and an audio interface means the app rewards users who manage hardware, while ToneCloud gives less experienced players access to community-created tones without running every profiling session themselves.

A focused choice for players invested in their physical gear

REACTOR is a practical option for musicians who want to preserve and carry their tonal identity into different contexts. It favors users prepared to work with hardware and profile sessions, rather than those seeking an immediate, hardware-free solution. For committed players who prioritize consistent tone portability across practice, studio, and live setups, it delivers a clear path to maintaining signature sounds.
