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.

Normally amazing
Color: Spiky Ball (Blue, Orange), Size: Medium
We have purchased these slightly spiky dog balls several times for our very strong jaw heavy chewer dogs and they’ve been amazing. They don’t break down they don’t get torn apart the squeakers don’t even pop out of them. So we ordered another package because we’ve lost a few outside to the lawnmower… oops and the package that got delivered today had only one ball that squeaks and the other does not. THIS IS A PROBLEM ! Unfortunately my female dog got to the new squeaking ball first and my male got to the non-squeaking ball and he was NOT happy. Basically once they claim a ball it’s theirs and the other dogs don’t go near the ball they claimed. So he’s following my female around and every time she squeaks the ball and I’m just waiting for him to attempt to take it from her causing damage to her. Normally… These are amazingly fun, tough, durable but also squeaking balls (that’s rare in a tough ball) that my dogs absolutely love. This time just got a bad batch I guess. When they squeak the dogs LOVE them. After several months of play the squeaker might break inside of the ball but the ball never comes apart or gets damaged. And we as the owners love that they don’t break down are not able to be ripped or torn even by our very strong jawed and big jaw muscle dogs. They are also great for in the house play because they’re small enough that they fit completely inside our dog‘s mouth but obviously not small enough to get swallowed so when we throw them in the house for fetch the dogs can jump up and catch them fully in their mouth so they don’t cause any damage to the walls when they hit the walls. They’re not super heavy but they’re incredibly durable. Definitely worth the price especially if you have heavy chewers or big jaw muscle dogs.

Best fun indestructible toy
Color: Crinkle Duck (Yellow), Size: Large
Truly indestructible no matter how much our oittie tries. She has owned it for three months works at destroying every day with no success. She carries it everywhere. Best purchase for chewer, more fun than the popular rubber heavy duty toy. Do not hesitate your pup will thank you for this fun distraction.

My dog loves this toy!
Color: Bunny (Gray), Size: Large, Color: Bunny (Gray), Size: Large
High quality, big toy, perfect for a medium to large size dog. After a few months of serious chewing I had to buy another one, but well worth the money! Rocky loves it.

Great toy but if your dog is an aggressive chewer, please think twice.
Color: Crinkle Chicken (Brown), Size: Large
I received this on May 23rd and on June 8th, after playing with this thing every day, our recently acquired 36 lb dog finally ripped it open and got out all the plastic and the squeaky part. Lily Belle will miss you, chicken. Lily loooooved this toy! She'd toss it in the air, chew on it, pull it with her teeth etc. but as much as she loved it, we won't replace it. It's just not durable enough for her. If your dog is an aggressive chewer, you might want to try a different toy. I hate that this lasted just a smidge over two weeks because Lily seemed to truly enjoy this toy. RIP, squeaky chicken!

Great Value Toy
Color: Crinkle Duck (Blue), Size: Large, Color: Crinkle Duck (Blue), Size: Large
This toy has been one of my dog’s absolute favorites. He gets excited every time he sees it and will carry it around the house, toss it in the air, and keep himself entertained for a long time. The shape and texture seem perfect for him, and it quickly became one of his go-to toys over everything else in his basket. What I really like is that it holds up reasonably well for the price. It’s definitely not indestructible, and after a lot of play, it will sometimes start to rip—usually around the feet first since that’s where my dog tends to grab and chew the most. But honestly, considering how affordable it is, I don’t mind replacing it when needed. It’s inexpensive enough that rebuying feels worth it because he genuinely loves it that much. I’d rather keep buying a toy he is obsessed with than spend more on something that just sits untouched. It’s fun, cute, and keeps him happy, which is what matters most. Overall, I’d definitely recommend it for dogs who love plush toys and playful chewing.
