Saves my amps' lives!

I live in a place with very high current from the wall and have a pile of vintage amps. With the Brown Box, I can guarantee I'll get the same power and tone while extending the already long lives of these amps. I can't leave for a gig without it!

If you love tone and have a tube amp....you need this...just buy it.

I was a bit skeptical, I've bought my share of snake-oil devices that didn't do anything noticeable....but I tried the BrownBox....Well, I plugged my amp into it...plugged it into the wall...and turned the voltage from my wall (123v) to 110 and WOW! It really brought my amp to life…I thought it was really great without the BB but after turning the voltage supply to 110….it’s noticeably better! It sounds and feels great.

Excellent quality tone tool

Required imo for vintage amps with modern wall voltage where I live.
