Guitar processors like the Axe-Fx can recreate the sounds of the greatest amplifiers and effects of all time. Studio monitors, though ideal for recording, can fall short of recreating the experience of playing through a real guitar amp. A high end PA delivers great tone from your rig to the audience, but what about on stage sound, or rehearsal, or private practice? For today's advanced guitar processor, you need a system which delivers high full range quality audio with the familiar feel and format of a real amp. Enter the Reactor Series.
The Reactor Series delivers the performance of a full-range flat-response ("FRFR") system in a format that also brings the qualities that guitarists have sought since before the dawn of rock 'n roll—punch, power, and presence. The sound quality is outstanding—wide, smooth and accurate—with performance one would typically expect from much more expensive systems.
The Reactor FR Cab is ideal for those who want to stand in front of their amp in a traditional setup. The Wedge was designed to be placed on the floor and aimed up at the player, though some players also stand this model on end for a more traditional backline experience. Our standalone power amp, the MB-50, can power your current guitar cabinet with 50W of transparent amplification -- allowing you to enjoy the benefits of your modeler's guitar power amp simulation while pushing real speakers.
While the Reactor Series was designed for use with full range guitar amplification, these products are also ideal for a broad range of other musical instruments and applications, including acoustic guitar, guitar synth, keyboards, backing tracks vocals, and more. All products sold by Atomic Amplifiers come with a 15-day money back guarantee. Buy it, try it, and if you are unsatisfied for any reason, we’ll accept your return and refund the purchase price (excluding shipping).
See below for more information about the Atomic Reactor Series.
The Reactor 50/50 Rackmount Stereo Power Amp is driven by two independent power sections based on those in our wedge/cab/mono block with upgrades and improvements to the power supply and other areas. It features front-panel bias controls, versatile i/o including XLR and 1/4”, and dual independent level/presence controls. It ships with JJ 6L6GC tubes and works with a range of replacements including EL34.
