Learn How to Use the BrownBox
I thought my amp was pretty badass and couldn't ask for more... when I heard the Johnny Hiland vids I knew there was something to this box and pulled the trigger. Well, it astounded me, I'm so glad I took the leap - wish I'd got it sooner, but better late than never!
Let customers speak for us
from 82 reviewsLove the Brownie. I have not been able to find anything that would make it B Stock - did you guys acidentally put a new Brownie in a B-Stock box? It works perfect delivering 117 VAC to my Mesa Boogie which is by the way what the user manual calls for!

BrownBox has been instrumental in keeping my vintage Ampeg SVT operating flawlessly on the road, where voltages can fluctuate wildly!

congratulations to the team of AmpRx

Excellent product. Just what I needed for my vintage 1950s Fender amps.

Really like this unit.
What sold me for this product was Dan, Mick from the pedal show on you-tube and the ability to plug in multiple amps via the 4 receptacles in the back.

I can’t explain how happy I feel with the BrownBox. The difference was immediate — more clarity, cleaner tone, more headroom. I connected my vintage Fender Bassman and Matchless (my oldest amps) and wow, what a relief to know they’re running at the right voltage and not suffering anymore. The sound is so much more alive and natural.
If you care about your amps, especially vintage ones, this is a must. It gives me peace of mind and the best tone I’ve heard from my gear in years. Absolutely recommended!1000 stars!!!! Daniel Uribe

Great pedal for modern amps. I live in the Mojave desert and AC is actually too low at times (115v). Being able to bump up the voltage is very useful. Overall, I suspect that the filtration in the unit contributes to a smother performance and sound, whether or not you are altering the AC.

I love The Brownbox! I now have 2 of them and my '72 Marshall Super Lead and '98 Mesa Boogie loves them too! They definitely make a difference in tone and I feel safe that they are running at the voltages that they should, btw extremely fast shipping from AmpRx which I felt I had to mention. Thank You AmpRX!

Great company and Great product!!

Absolutely LOVE AmpRx products.
I bought the Brown Box...leading me to buy the Power Station 1200.....my amps have never reacted and sounded better.
Keep up the Awesome work!

I 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!
