## What is REACTOR?

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.

### 2/5 — Will not connect to the app

*2026-08-16*

Have sat here for an hour now trying to get this amp connected to the app how frustrating and a shame it promised good things .

### 5/5 — Best

*2026-08-12*

Amazing

### 1/5 — Huge fail on iPad

*2026-07-11*

Does not have a native iPad app. It runs the phone app with poor layout. Big fail.

### 5/5 — Funktioniert top!

*2026-07-09*

Die KI Bilder sind nicht jedermanns Sache, aber am Ende kauft man den Reactor wegen dem Sound und den Möglichkeiten die man über die App hat und das funktioniert alles wirklich 1A. 

Natürlich liefert die KI nicht direkt den Perfekt Sound, aber man ist schon nah dran und kann dann schnell selbst nur noch ein paar Einstellungen vornehmen um da gewünschte Ergebnis zu erhalten.

Bin genauso begeistert wie vom Spark, nur dass der Amp hier natürlich dazu noch 100x besser klingt.

Weiter so, Positive Grid!

### 5/5 — お願い

*2026-07-08*

最高のアプリとアンプです。
楽しくて仕方ないですが、ひとつだけ、→ チューナーの周波数に442Hzを選べる様にしてください、管楽器とのアンサンブルで必要です、お願いします。

### 1/5 — iPad not working…

*2026-07-02*

iPad doesn’t launch app with OS 17.7.11. I’ve tried everything suggested and it still just freezes.

### 1/5 — Does not work on iPad

*2026-07-01*

Just a frozen screen on iPad (IOS 17.7.11) … wiped iPad, deleted iCloud data, reinstalled app … no worky

### 2/5 — Constant connection losses

*2026-06-27*

Update: the last version did also boot fix this for me.  I use iPhone 16. 

—-

While the Bluetooth connection from my iPhone to the reactor rock solid where I can stream music from 15 m away easily the connection of the app to the amp is lost when I move my app more than 30 cm away from the amp. And I can only reconnect to the amp if I am that close. I don’t know, but this does not make sense to me.
The rest of the app works very well. I’m just very limited in my movement area.

Anyway, I love the product and I really enjoy the app.

### 2/5 — Buggy

*2026-06-21*

App is buggy. Switching tones takes multiple clicks all the time. Can’t click the 1sr search result on ToneCloud searches. AI gives “unknown error” a lot of the time. Needs refinements.

### 4/5 — Very good and the amp is amazing. But I wish it was optimise better for iPad.

*2026-06-21*

Please optimise the app for iPad. it would definitely be five stars if it wasn’t for that because I use an iPad as my interface other than that it’s great. 👍
