Optimal voltage for a superior tone!

If you want to get the most out of your tube amp, you need a BrownBox!

Tube amps are designed to run at an optimal voltage, and standard 120V/AC wall current is typically too high for them.

The BrownBox lets you bring the current down to an optimal level, resulting in significantly improved amp performance.

Another benefit of running your amp at the optimal voltage is that your tubes will usually last much longer.

Whatever the venue, you’re sure to supply your amp with the optimal input voltage for your personal sound!

 

AmpRX BrownBox Voltage Attenuator features:

• The perfect way to optimize the input voltage for your tube amp.

• Dramatically improves your amp's performance!

• Optimal input voltage extends the life of your power tubes.

• LCD voltmeter makes it easy to dial in the optimal setting for your amp.

• Selectable input current setting ensures safe and accurate operation.

• Choose from 4 attenuation modes to fine-tune your voltage.

• Bypass mode lets you easily A/B the results of your optimized amp voltage.

• Braced metal chassis and protective bar withstand the most brutal touring conditions.
