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

Super fast shipping A+++

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!

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…… 😎

Thank you!

If you want your amp to be consistent between home, rehearsal, stage, and studio, just buy one. Carry it with you and use it everywhere. It's killer. Then buy at least one spare just in case.

Love this thing. My amp sounds better and the customer service and ease of use is incredible.
