About this app

Your imagination deserves an amplifier.

REACTOR is the companion app for the REACTOR intelligent guitar combo amp — powered by Amp Intelligence™, a sound engine trained on over 1 million tones and the circuit-level DNA of 200+ legendary amp designs. Type an idea. Snap a photo. Drop in a recording. REACTOR builds the full signal chain in seconds.

CREATOR HUB — THREE WAYS TO BUILD TONE
• Audio to Tone. Upload a track or record a clip. Amp Intelligence analyzes the sound and rebuilds it as a playable guitar tone.
• Image to Tone. See an amp, a pedalboard, or a setup that inspires you. Snap it. The app turns the photo into a matching tone.
• Text to Tone. Describe an amp, an artist, or a feel in your own words. Amp Intelligence figures out the signal chain and makes it playable.
• Build your own amps. Combine characteristics, shape deep parameters, and create original amp voices that don't exist anywhere else. Name them, save them, share them.

DEEP CONTROL, INSTANT CHANGES
• 24 amp models to start — full parameter access to gain structure, EQ, bias, and voicing
• 8 simultaneous effect slots across Gate, Compressor, Drive, Modulation, Delay, Reverb, Wah, and EQ
• Drag-and-drop signal path — reorder effects anywhere, insert the FX loop at any point
• Unlimited preset library, organized by song, session, or genre
• Assign presets to 8 onboard amp slots for instant recall on stage
• Built-in tuner

TONE MEMORY
REACTOR remembers your prompts, inputs, and adjustments. Every time you create, it starts closer to the sound in your head.

TONECLOUD
Browse and download tones and custom amps from other players. Share your own. Discover patches built by artists and the global REACTOR community.

CONNECTS TO YOUR AMP
Pair over Bluetooth or Wi-Fi. Push presets and custom amps to your REACTOR combo amp. Pull them back to the app to edit, refine, or share.

Now tone answers to you.


Requires a REACTOR 50 or REACTOR 100 amp for full functionality.

Let me start by saying that the amp and sounds are first rate. I also have been getting email feedback from Reactor that has been timely and helpful. Now let me get to the app. I don't find the app intuitive and laid out to just breeze through. Instructions for using the app past the most basic stages is more labor intensive than necessary. I had problems with using the feature that uses my phone mic to create. I will update their team, as they seem genuinely interested. Overall I like it.

another company injecting itself with AI for short term gain. even the in-app art is AI generated and it looks like slop. I dont need a compressor to look vibey, I need to know what analog hardware its emulating. it stands to reason that they will soon stop supporting their old hardware so they can chase this new ai-ridden bag. I liked the spark ecosystem for all its flaws, and this new direction seems to be straight down.
