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.
When using the Amp Intelligence to create tones, there are times when I click on one of the options presented and it acts like the signal isn’t being received by the amp hardware correctly. There will either be no change in the amp tone, or the amp will sometimes go into what sounds like some sort of feedback loop.
Kind Of A Let Down
Truth?73
I really was excited when this was announced. The 50 watt amp sounds good and is easy to set up; you could actually play a small gig with it. The let down is the app and controls. It honestly is not much different than the AI on my little Spark amp. Not much different at all. My advice is if you are looking at going this kind of route, buy a good DAW and use whatever your preferred sim app is and run it to your phone or iPad if you’re using this live, get a good switch pedal. I would rate this higher if you could also record. That is the main reason I bought this as it was kind of misleading as to how they advertised this. My I-Rig HD is way more versatile. In closing this was a disappointment. Not much different than using AI feature on my Spark.
Works well

I use it on an iPad and it’s not set up to look right when in horizontal view. Still works fine just doesn’t look great. Looks better in the iPhone
Thank you for the update - iPad works!
