Brownbox II By AmpRX
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.

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.
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!!!
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!!
