AmpRx is a brand based in Nashville, USA. The small AmpRx team 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 from your power outlet and arriving at your amplifier. Energy suppliers are not very particular about the stability of the current supplied.
The result? Your amp, pedals, and entire sound system benefit. You simply sound better, all the time, with the same sound no matter where you play.
A must have for all tube amp users.
