Positive Grid Reactor 100 Intelligent 100 Watt 1 x 12 Guitar Amp Combo

Positive Grid built the REACTOR 100 around Amp Intelligence®, a tone engine trained on over one million recordings and reverse–engineered from more than 200 amp circuits at the component level. Rather than merely simulating classic tones, it decodes how real amplifiers behave: gain structure, output transformers, bias settings, and harmonic generation. The result responds like a tube amp should—organic, dynamic, and alive under your hands. This 100–watt flagship sits at the top of the range, built for players needing serious headroom and projection through a custom–voiced 12” speaker with premium magnet.

Select between 100W, 25W, or 1W output without compromising tone. Creator Hub lets you generate a complete signal chain in seconds: describe your sound in text, photograph an existing rig, or upload an audio sample and Amp Intelligence builds it for you. Twenty–four amp models ship standard, with unlimited custom amp creation via the REACTOR app. Eight effect slots cover Gate, Compressor, Drive, Modulation, Delay, Reverb, Wah, and EQ. Save eight presets onboard; store unlimited chains in the cloud via ToneCloud. USB–C direct recording includes cabinet simulation. Connectivity spans Bluetooth audio, MIDI In, effects loop, line and headphone outputs, and power amp input.

Push and Smooth controls plus Heat adjustment (–/+) let you reshape tone on the fly during gigs. The wood cabinet and custom speaker voice deliver natural projection in small rooms and larger venues alike. Remote control via optional REACTOR Control pedal (sold separately) extends hands–free operation. Firmware updates arrive over Wi–Fi, keeping the tone engine current.
