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.

Great Quality, but Check Cabinet Height Carefully
Item Package Quantity: 2
I am so, so sad these iSpecle Pull Out Spice Racks did not fit in my kitchen cabinets. I thought I had checked, but the most my cabinets can take with the nonadjustable shelves is 9", and these are a little over 9.5" tall at the metal rack side. They may not fit where I intended to use them, but they appear to be good quality and really help with organization. They look nice and slide in and out well, so I fully intend to find another way to use them. Maybe under the bathroom sink where smaller items also like to cluster.

Finally solved my spice cabinet chaos
Item Package Quantity: 2
I didn’t realize how much time I was wasting digging through my spice cabinet until I installed these. My spices used to be stacked behind one another, which meant every time I needed a specific seasoning, I had to move half the cabinet around just to find it. These racks completely solved that problem. What immediately appealed to me was the no-drill installation. I rent my home, so I’m always hesitant to make permanent changes to cabinets. The peel-and-stick setup was surprisingly easy, and I had both racks installed in just a few minutes. Once attached, they felt much more secure than I expected. I was initially skeptical about adhesive mounting, but they’ve stayed firmly in place. The pull-out design is where these really shine. Instead of reaching into a dark cabinet and searching through rows of jars, I can simply slide the rack out and instantly see everything. It’s one of those organizational upgrades that makes everyday cooking noticeably easier. I also appreciate the adjustable height feature. My spice collection includes a mix of different bottle sizes, and I was able to configure the racks to accommodate both smaller and larger containers without any issues. The flexibility makes them much more useful than fixed-size organizers. Another thing I noticed is how much cabinet space they helped free up. By using vertical space more efficiently, my cabinet feels less cluttered and much more organized. I can now find exactly what I need without knocking over other jars or creating a mess. The overall construction feels sturdy, and the sliding action remains smooth even when the racks are fully loaded. This is one of those products that seems basic but ends up making a bigger difference than expected. If your spice cabinet is crowded, disorganized, or constantly frustrating to use, these racks are an easy solution. They’ve made cooking more convenient, improved organization, and helped maximize storage space. For me, that’s an easy five-star product.

Finally, a Spice Rack That Fixes the Real Problem—Access Without the Hassle
Item Package Quantity: 2
I am pleasantly surprised at how handy this spice rack is!! This iSPECLE pull-out spice rack does that others rarely deliver... makes your daily routine just that much easier. The biggest win here is access. No longer having to rummage through a messy cabinet or knock over jars to retrieve whatever you’re looking for. With everything just sliding out and coming up right in front of you. The idea is simple, but it creates a difference. There's your strong point here: the no-drill, peel-and-stick installation. It’s simple and time-saving, which is something. That being said, it still needs to be installed correctly. Use a clean surface, pressure, and time to set. Do that, and it holds well. Overlook that step, and you’ll be blaming the product when it’s all set up for you. The adjustable height is practical, especially if you’re working with a mix of 4oz and 8oz spice jars. It’s not flashy, but it offers a solution to the same annoying problem: trying to cram mismatched containers into a rigid system. What impresses me the most is that it provides some order rather than making things ever murkier. It’s not looking to reinvent your kitchen. It takes a common frustration (buried spices in dark cabinets) and makes it neat and clean for practicality's sake. Bottom line: If your cabinet seems like a black hole of spices, this is an easy, straightforward solution. Not anything fancy, just smart design and it works!

Be Mindful Of The Height
Item Package Quantity: 2
So this spice rack is amazing, if you know what you're getting. I have had a similar one in the past that was just one level. It was great and made organization easy. This being two levels tall means you have to take that into account because it's going to change the shelve layout in your spice cabinet. It wasn't a problem for me and still ended up being a net positive for making the most out of the space, but my friend bought the same ones and ended up sending them back because they wouldn't fit into his smaller cabinet. If you are aware of that going in and know it's going to work for you, they are amazing. They slide smoothly, they hold a ton, and make getting to the items in the back infinitely better. Decent price for such a huge quality of life improvement for my kitchen.
