Note: This product has been merged with the Original BrownBox. The OG BrownBox is now 50/60hz. The BrownBox II has been retired. 

Only a few left at this special price!

All the goods as The Original BrownBox, but made for 120VAC at 50/60 Hz when powering American amps in 120V countries or with a stepdown transformer overseas

Input: 120VAC, 50-60 Hz; Standard IEC AC cable
Output: Two AC Grounded Outlets, Adjustable Voltage Reduction
Power Handling: 5 Amps at 120VAC, 50-60 Hz, up to 540 Watts

WHY WOULD YOU NEED A BROWNBOX II? 
If you’re overseas - say, in a 220V country - but you’re using an amp that has a 120V power section, you’ll need a BrownBox II. Maybe you’re on tour and brought your own amp - maybe you live in a 220V country but you own an American powered amp. You can’t just plug it into the wall - you need a step down transformer to get from 220V to 120V - and then you can use the BrownBox II.

WHY NOT JUST USE A BROWNBOX? 
Not all step down transformers are frequency compensating - that means that what you’re probably getting is 120V / 50Hz. That will fry an Original BrownBox - which is only meant for 120V / 60Hz - like an egg. To safely use our products with a step-down transformer, you’ll need a BrownBox II.

CAN I USE A BROWNBOX II IN NORTH AMERICA?
Absolutely. The BrownBox II accepts 50 Hz and above, so it is safe to operate it at both 120V/50Hz and 120V/60Hz. If you’re not taking the BrownBox out of North America, you really don’t need a BrownBox II - but YES, it will safely work.

Awesome stuff

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

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...

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.
