What is BrownBox?

BrownBox is a device that allows you reduce the voltage going to your amplifier.

Why do you need this?

Musicians may not be aware that the voltage emanating from standard AC sockets in commercial buildings can range anywhere from 115V to 130V.

But what if you want to provide consistent voltage to your amplifier wherever you go? How do you cope with the wide variation in voltages?

BrownBox was designed to solve this problem.

AmpRX Origin and Current Owners

AmpRX was founded in 2014 by inventor and guitarist Pat Geraghty. In 2022 he sold the Maryland-based company to Nashville-based professional musicians Cassandra Sotos (violinist) and Clark Singleton (bassist).

Sotos and Singleton were already sold on the company's merits; they had already used BrownBox attenuators professionally before buying the company.

BrownBox's pro-player customers seek optimal tone, consistency, and enhanced equipment lifespan. No wonder the AmpRX has been a huge success.
