Boasting 50 watts of guitar-driven firepower and component-level modeling, the Reactor 50 is here to set the new standard for modeling amps. Driven by AI-powered Agentic DSP Amp Intelligence, the accompanying Reactor app, and a familiar top-panel control layout, you control every parameter, setting, and component to create your ultimate guitar tone. Dialing in a tone is as simple as describing the sound you're after or uploading an audio clip for Reactor to analyze. Reactor even responds to conversational tweaks. Once configured, the Reactor 50 explodes with touch-sensitive dynamics, courtesy of Positive Grid’s BIAS X engine and the custom-voiced 12-inch loudspeaker. A gamut of other features is yours to command, including eight recallable presets, six built-in effects with Tap Tempo, and a multi-watt power selection that allows the Reactor to adapt to any environment. You'll also receive an external effects loop for your own stompboxes, remote control options, Headphone Out, Line Out, and a USB-C audio interface for recording, ensuring the Reactor 50 is ready to tackle virtually any practice or performance situation. Primed for the ultimate tone-shaping experience, the Reactor 50 melds brains and brawn to deliver the best elements of sonic experimentation and high-octane performance.

A command center at your fingertips
The Reactor 50 features an intuitive experience for dialing in your favorite tones. You get six amp models, from Clean to Extreme, along with Heat and Push-Smooth switches to refine the overall gain structure of the selected amp model. Six built-in effects transform your aural foundation into soaring soundscapes, twangy slapbacks, and mountaintop-style leads with ease, and the Reactor 50’s external effects loop integrates your existing pedals directly into the amp’s tone stack. Once you’ve sculpted your sonic masterpiece, it can be saved and recalled in one of eight presets.

Unlimited creative freedom with the Reactor app
The Reactor app, connected via Bluetooth on your smart device, is your gateway to complete creative expression. Every parameter on the Reactor 50 can be fine-tuned to perfection. Even more, you get access to Positive Grid’s AI-powered Agentic DSP Amp Intelligence to create profiles of your favorite gear or design a new sound entirely. Simple yet intuitive, the Reactor app offers three options to let your imagination soar:

  • Text to Tone: Using the Reactor App’s chat prompt, simply type in your desired sound and the app gets to work. Need to make an update? The Reactor app responds to conversational tweaks, like, “Add compression," or “Less gain," making editing a simple endeavor.
  • Audio to Tone: This feature analyzes any uploaded audio file, then uses timestamps, either automatically detected or manually specified, to build your rig of choice. Whether you upload an isolated guitar track or a full mix, the Reactor app will analyze every eccentricity of the tone to deliver an astonishingly accurate re-creation.
  • Picture to Tone: Snap a photo of your favorite pedal. Capture the perfect sunrise. Upload a selfie. The Picture to Tone feature accepts any image and transforms it into a tapestry of sound befitting of the given image.

Stage-ready control
When it's time to take the stage, you can trust that the Reactor 50 will push more than enough power to keep up with your live band. Its 50-watt power section and custom 12-inch Reactor loudspeaker deliver authentic guitar sonics, with an emphasis on the low to low-midrange frequencies that ensure punchy tone and limit piercing highs. Sound engineers will also delight in the Line Out jack, which allows you to send your amp's signal directly to the venue's sound system, no miking required.

With the optional Reactor Control pedal, you can unlock instant access to all eight of the amp's presets and effortless effect switching. Moreover, the included MIDI input allows remote switching either with your own MIDI foot controller or via program change automation, ensuring the Reactor 50 can integrate seamlessly with larger audio and video productions.

The most engaging interactive toy for my Border Collie
Color: Orange, Color: Orange
My Border Collie is not a big ball player. He prefers tug type games and actually gives me a look like, “Are you stupid? I’m not going to keep bringing that to you if all you’re going to do is throw it away again!” after about the third time I throw a ball for him to fetch. However, I can only play tug so often and I need him to be entertained and engaged as much as possible. I got him a smaller, non-padded ball like this hoping he would like the interactive aspect of it. He did- he actually loved it! But it was loud, hard on his teeth, would come apart periodically, and he kept hitting the off button when playing with it. It drove me crazy. This one is so much better overall! The soft outer shell is not only easier on his teeth, but it is super resilient to biting and chewing. He actually likes to carry this thing around in his mouth while it’s bouncing and vibrating. The three modes give great flexibility for different kinds of play. His favorite is the most active mode: the ball reacts to touch and practically bounces itself across the floor when he touches it with his paw or mouth. I will point out that in one of the modes, I thought the battery wasn’t charged or there was a motor issue because it’s very subdued movement; however, it’s just set up as a low-key option. Be sure to check out each mode to see which works best for your dog at different times. I can’t say enough about this ball- I have been so pleasantly surprised by how much he loves it. The rechargeable feature is super convenient, it’s big enough to not get stuck under the couch, and it automatically shuts off based on whichever mode it’s set on. As the owner of a busy, super-smart dog who needs to be engaged in mental and physical activity, I think this all is worth every penny. In fact, I’m buying one for a friend who has a Border Collie pup with lots of energy to burn! I highly recommend this toy- it’s the most engaging toy I’ve found that Finn will play with on his own.

Not as Smart or Interactive as You Think it Will Be
Color: Blue
This is an honest review from a schnauzer owner who has has wanted this cheerble ball for their dog for more than one year. I finally bougI finally bought this toy and both me and my dog are disappointed. The settings are...i would say dog friendly as I'd assumed a dog ball would be. What I mean by that is, for example: the calm play setting is muuch too calm. Super light puffs of energy, like a battery is dying. And the playful setting is scary, alarmingly so. The intervals in between are too long. The ball does not bounce. So they just have settings all wrong. The size is good for a large dog only. Do not buy if you have a small to medium dog. I even think the material is okay. I've only had it for a few days so I can't even speak to how the material holds up. Really hoping to love this ball for my dog. It was not the distraction I was hoping it would be so I could work from home while my dog had fun. I'm hoping this can help someone else who's been pining over it. Essentially, it's a $35-$50 well made weighted ball that moves occasionally.

Light up and glow in the dark ball
Size: One-Size-for-Most
Definitely my girls favorite ball 😀. It disappears and I have to buy another one or she goes nuts. Glows in the dark, brighter with more sun. The bounce light up don’t last a real long time, too quick to quit for her but still loves it.

Durable & Bright - Great for Heavy Chewers
Size: One-Size-for-Most
Pros: Extremely Durable: Survived an aggressive chewer where tennis balls failed. Dual-Visibility: Features both internal flashing lights and a glow-in-the-dark "chargeable" surface. Perfect Size: Fits comfortably in the mouth of a 40lb medium-sized dog. Same size as a tennis ball. Cons: Battery Life: Unsure how long the internal flashing lights will last (though it has held up well so far).

Great for night time play!
Size: One-Size-for-Most
This ball is great! It is a 2-for-one light up feature so we love the flashing lights and if she drops it in the snow after those lights stop, we can still find it because of the strong glow that gets its charge from the flashing LED lights. Our first one lasted a few years, we lost it on a trip so now back for our second one so we can keep the night time fetch going! She is a golden retriever for size reference. Any bigger of a breed and I would worry it might be too small for her mouth. It’s a bit smaller than a tennis ball. Just don’t make the same mistake I did and let them have it in the house at night, she walked up to my bedside while I was asleep one night and squeezed it to activate it. Those lights are so bright it was a rude awakening!
