Positive Grid Reactor Amps

Positive Grid Reactor Amps

Positive Grid Reactor amps are seriously smart, blending cutting-edge tech with classic amp sensibilities. Available as 50W or 100W 1x12” electric guitar amp combos, these are flexible, genuinely inspiring tone machines for the home, studio and stage.

At the heart of the Reactor is Positive Grid’s groundbreaking Amp Intelligence sound engine. Rather than just loading presets, it builds tones the way you imagine them. Play a reference clip, snap a photo of a rig, or simply describe a sound — and Reactor creates a complete signal chain on the spot!

Better still, its Tone Memory feature learns what you like the more you play, meaning every tweak gets you closer to your dream sound. Combine that with selectable wattage on both models, and you’ll get consistent tone whether you’re practicing quietly in your lounge or cranking things up at a gig.

Classic feel, powered by intelligence

Reactor electric guitar amps don’t forget what matters. Built with sturdy wooden cabinets, custom 12” speakers and intuitive controls, they deliver the punch, dynamics and clarity you’d expect from a traditional combo. Under the hood, Amp Intelligence has decoded over 200 classic amps down to their circuit level — think gain stages, transformers and bias points. So, you get authentic response with modern flexibility.

Three ways to dial in your tone

  1. Top panel: Tactile knobs give you easy access to gain, EQ, effects, master volume and preset recall. Mod switches let you tweak in new and unique ways, and you can go even further with easy amp and effects selection.
  2. Reactor app: A drag-and-drop tone studio with Amp Intelligence-powered tone generation and visual signal chain editing.
  3. Reactor Control footswitch (sold separately): Featuring six switches and expression support, with the ability to use it wireless or wired. It’s perfect for live performance!

Build tones with Tone Capture

Using Amp Intelligence, Creator Hub’s Tone Capture feature lets you craft sounds in three ways:

  • Audio to tone: Drop in a clip and Reactor recreates the guitar sound to match.
  • Image to tone: Take a photo of an amp or pedalboard and turn it into a playable rig.
  • Text to tone: Describe a sound, artist or vibe and let the amp do the rest.
