LEARN ABOUT THE BROWNIE
Today, we should be receiving 120V AC from the wall, but depending on where you are and what time of day it is, you can receive anywhere from 120V to 129V. That’s not good for your amplifier, or your ears. The Brownie is a voltage optimizing power supply (aka a voltage controller) designed specifically for modern tube amplifiers, offering the ultimate solution for achieving consistent tone and protecting valuable equipment - the first of its kind.
The Brownie is the first product in the AmpRx line to increase and decrease voltage. Plug the Brownie into the wall, adjust the voltage and then plug your gear into the Brownie.
WHAT MAKES THE BROWNIE SPECIAL?
Modern Versatility: The first product in the AmpRx line to both decrease and increase voltage, compatible with all amplifier types from classic tube amps to modern designs.
Unlock the Perfect Tone: Achieve consistency in tone and protect gear in any environment by dialing in the voltage you need every time you power your amp. Love your tone at 117V? You got it.
Serious Protection: Mitigate disaster. Prevent unnecessary, expensive, and frustrating repairs.
Industry Recognition: AmpRx is trusted by amp techs around the world, top touring artists and their techs, and has been spotted on stages with artists like the Red Hot Chili Peppers, Paramore, Bonnie Raitt, Derek Trucks, Iron Maiden, Lynyrd Skynyrd and more.
Designed for All Musicians: Priced at $299, the Brownie is an affordable way for all musicians to attain professional-grade voltage control.

Learn How to Use the BrownBox
This thing is awesome, it does what the Brownbox does and more! You can dial down the voltage OR dial it up if need… the world is better because of this little dude… it fits in the back of my amp, it loves me, it helps me not blow sh*t up, if only it could make me a sandwich….. hmmm…… 😎
Let customers speak for us
from 70 reviewsI really like the Brown Box. Thanks a lot.

Takes that brittle edge off the top of my Bassman. You don’t know you need it till you get it. Eases stress!

I’m very happy with my purchase of the Brownie. It’s more compact than the regular Brown Box and more suited to the types of amps I gig daily

If you play vintage tube amps from the 50s or 60s you need one of these. You'll be able to tell instantly that you needed it all along...

Shipping was fast, and I got my second "Brownie" in, it looks and operates just like the non B stock Brownie, and at a discount price!

Received my AmpRx mugs patches and swag. Y'all are life savers. Just rack3d my new Power Station 1200...an absolute amp saver. My tracks have never sounded better. Keep up the great work!!! - Coop

The Brownbox is an essential piece of gear. All of my new and vintage amps sound better with the brown box. My house has 123-125volts, everything sounds a little hard at that voltage. Reduced voltage makes my black face amps creamier and my tweet amps sweeter.

I love this with shirt. Purchased it with an extra patch.

Thanks for processing the order quickly and the fast shipping!

Great Customer Support

Yep. Does what y’all say it does. Got an old Deluxe (as most do, I suppose), that sounds better than it ever has. Hell, I’m even using it with old tube mics, pre’s & compressors. ALL sound … well … better - thanks!

This is a tour grade, durable little box! Easy to dial in, and a good safety measure for spikes in power etc. I also like that you can feel a differences. For my '65 Bandmaster head, I find that the BrownBox smooths out the high end and gives the response a fuller, rounded out feel by lowering the voltage to 117v. Thank you AmpRx!
