AmpRX : The Reference in Voltage Optimization for Tube Amps
AmpRX is an American brand pioneering the development of voltage regulation solutions for tube amplifiers. Founded by guitar and audio enthusiasts, the brand's mission is to enable musicians to run their amps under optimal voltage conditions, thus preserving their original sound and extending their lifespan. With iconic products like the BrownBox, the Brownie, and the Apparition wireless interface, AmpRX has become an essential player for guitarists worldwide, from vintage amp owners to stage and studio professionals.
AmpRX : The Revolution of Voltage Control for Tube Amplifiers
AmpRX is an innovative brand specializing in voltage regulation and optimization solutions for tube amplifiers. Its flagship product, the BrownBox, is an input voltage attenuator designed to provide a safe and precise voltage reduction range for vintage tube amplifiers. In a world where modern mains voltages (often between 120V and 125V) far exceed those for which vintage amps were designed (105V to 115V), the BrownBox allows you to recover the authentic sound and original dynamic response of these legendary amplifiers.
The BrownBox stands out with its simple two-knob design including a primary voltage selector and a reduction level knob. It also displays real-time voltage and current, giving you total control over your amp's power supply. Whether you own a 1950s Fender Tweed, a Marshall Plexi, or a Vox AC30, the BrownBox lets you adjust the supply voltage to make your tubes run exactly as they should, extending their lifespan while improving sustain, compression, and sonic clarity.
The Brownie : The New Generation of Voltage Optimization
Building on the success of the BrownBox, AmpRX launched the Brownie, the latest innovation in voltage optimization. More compact and even more intuitive, the Brownie offers musicians unparalleled control, flexibility, and protection for their equipment. Designed for modern guitarists who want to preserve their amps while exploring new sonic textures, the Brownie represents the culmination of years of research and development at AmpRX.
Apparition : Wireless Effects Switching
Beyond voltage regulation, AmpRX also offers the Apparition, a revolutionary wireless effects switching interface. Equipped with 4 effects loops, the Apparition allows you to control and mix your effects pedals like never before. Its innovative design frees you from the constraints of traditional cables and offers total flexibility to organize your pedalboard. The Apparition will make you rediscover your current setup by multiplying its possibilities like never before.
