I have one and they are a terrific tool if your mains voltage varies. I use it for an older amp that needs lower voltage and with newer amps to get the mains to 120vac (US wall voltage). It’s also important to note that valve heaters work best at 6.3v. Too high a mains voltage can run the heaters near or past the max spec for the valve and cause early failure.

Also remember tube amps are like living/breathing things and they will sound different when fully warmed up. And of course our ears change all the time too. And the atmospheric pressure, and on and on. Good idea of taking the wall voltage out of the equation though. Very well done video, and love both of your playing. 😎

[@steveburroughs7343]

Can you run more than one thing off it? Eg two amps & pedal board?

[@seventwistsclockwise]

I could be wrong but voltage does not blow fuses it is the current.

[@matthewf1979]

It’s total power that blows fuses. A combination of both current and voltage. Most glass type fuses are rated at 250VAC and a specific current.

I bought a fantastic CLARK tweed deluxe, in uk, so I've just ordered this from you.

[@bluesbothers]

Just ordered one to protect my Bloomfield. Thank you for the video!

[@PeterMoore350]

Oz and NZ is supposed to be 240V si suppose something like that would show us what’s being delivered

[@hekakain4108]

242 volts down to 195 volts...lovely bit of kit. UK. Friedman Runt 20 Combo and Fender Blues Deluxe Western Noir Ltd Edition.

[@j.rozman7016]

Great device! To my ears: 225 V sounded best! What is the best Voltage for Tone King Imperial MKII? Thanks!

[@MaximilianMengwasser]

My preferred Voltage for the Tone King Imperial MKII is 220V.

[@daviddixon7326]

My version allows me to plug in two amps. Not sure if that is still an option on these versions. But that’s a ‘game changer’ for me

[@skaboosh]

I'd use a small plug board to share the voltage

[@kristanbenson803]

I’m a bedroom player through a fender blues delux, is it worth getting one?

[@PeachGuitars]

100%!

[@tuspecatuspeca2885]

Grazie per il video, molto esplicativo! Ma io ho sempre avuto il problema contrario cioè ho trovato molto spesso nei posti dove suonavo una tensione più bassa, mi sembra di capire che il brownbox può solo ridurre la tensione? Oppure mi sbaglio? Grazie

[@PeachGuitars]

Hey, thank you for your question. I hope the Google translation I found is accurate. If I understand correctly, you are asking if the Brown Box can increase the voltage as well as reduce it? Unfortunately, this is not yet possible with the Brown Box. Apologies if my answer isn't what you were hoping for. However, the Brown Box is a piece of equipment that we really stand by and love here. If you are looking for something that can reduce the voltage from the outlet and provide a safe and consistent voltage to your amp, we couldn't recommend the AmpRX Brown Box more highly.

[@mykewright1]

But what does it sound like when powering a Modeler and FRFR?

[@RedArrow73]

Not the coorect application; this is for valve amps.

[@KevinGroce13]

you should played a e or a and drove the notes a bit to hear the different. you never play a guitar solo the same. the video is great. if you would have strum some chords this would have really dazzled.

[@danieldesjardins6615]

You can do the same thing with a Variac and a cheap multimeter for much less...and you can even raise the voltage if the grid voltage is too low, which is not the case here!

[@dougmishoe1336]

Isn’t this mainly for older amps?

[@peteyoung7665]

I would say yes.Older Marshalls from the 60's,70's should be run at 220 volts.And if there's 250 volts coming out of the wall you can blow up the transformer.But the brown box works well with new amps as well.

[@memygtar]

Do you no longer need step down transformers if you have a brown box?

[@shckltnebay]

It does not change the voltage from 220 to 110
