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.

BB II

I am a hard rock / progressive guitar player. I was playing around with different amps, pickups, speakers, cabs - you name it - to get to the tone that I wanted.
I noticed that somedays it would be close - I wouldn't change any settings, and then a day later it would sound dramatically different. I found that the outlet voltage varied quite a bit from day to day.
Once I got the AmpRX BBII - that not only provided a good amount of stability (in that area) but also got me to the tone that I love and use today.
It is a must have for my rig.

I am very glad I own a Briwn Box II

Recently I figured in a club where the mains voltage was 129 VAC bouncing up to as high as w 132VAC My gear is all vintage. Marshall plexi, black face Fender all old gear designed for 115-120 tops. So glad I bought this device and my sound is consistent. I lock in 127VAC for the best sound I ever had every night on every stage. No problem gigging in Europe either. Than you!!!

Works exactly as advertised

I have several amps, including some 1960s fender black panel amps, and this makes a notable difference in sound and consistency. I bias my amps at 117V and dial it in at venues as well- sounds great every time. Highly recommended!!

fantastic product !

I purchased this for my 1962 VOX AC30
It was designed to run at 115v

The voltage in our house out of the wall was 124V !!!
Way too much for this amp
So this product was perfect to maintain a constant 115V for my amp
