AmpRx is a brand based in Nashville, USA. The small team at AmpRx specializes in products for tube amp users. Don't expect a long catalog: there's only one product, the Brown Box!
This very useful, if not totally essential, accessory allows you to precisely adjust the voltage of the current coming out of your mains socket to power your amplifier. Since energy suppliers are not always very careful about the stability of the current supplied, the Brown Box allows you to compensate for these variations.
The result? Your amp, pedals, and entire sound system benefit immediately. You simply sound better, in every situation, with the same sound, no matter where you play.
A must-have for all tube amp users.
