AmpRX

AmpRX is an essential brand for any serious player with a boutique or vintage valve amplifier. They specialise in power conditioning and voltage regulation devices, most famously the BrownBox. The core mission of an AmpRX BrownBox is to allow players to set the optimal input voltage for their amp's circuit, compensating for the higher, often inconsistent wall voltage found in modern venues. This protection safeguards expensive valves and components, while the resulting tonal improvement is significant: better note clarity, increased harmonic complexity, and a more dynamic, "browned" feel. The product line, including the 220-240V versions, is relied upon by top technicians and touring professionals to ensure their valuable gear performs flawlessly and safely, revealing the true sonic potential of their circuits by supplying the power they were originally designed for.
