Does exactly what it says it will do, provides accurate, clean, and constant voltage to your amp. Voltages from your wall can and do fluctuate. Maintaining an input voltage that matches what your amp was designed for is essential.

Works as intended. I see no scratches on the exterior, and appears to be built like a tank.

AmpRx Sicky Sick!! Very Awesome!!

I've been playing places where previously my amp would break up to the point of distortion before using a drive pedal. Since the purchase of the Brownie and using at these venues I believe it's helped clean up my amp as it should be! Thanks AmpRx!

An amazing product from an amazing company. Every guitar player needs one !!!

Great product- Brown Deluxe likes 114 v

Solidly built, and able to dial in any common output voltage setting between the two knobs. The knobs themselves are large enough to grip, with solid detents that won't slip or be bumped out of adjustment. I worried that, unlike a Variac where you have a wiper-style adjustment, I might not be able to get exactly the voltage I wanted, but have found this to be a non-issue with any normal wall receptacle power. My amps like getting the right power and, unsurprisingly, sound best at the input voltage they were designed to use! It is nice to always be sure they're getting the voltage, both for tone and component longevity.

makes my old Princeton sound better than ever

Such a great device to dial in my tube amps

I use this after my power conditioner to lock in the voltage for my Ampeg Heritage bass tube amp. We play in a lot of places with improper voltage and this is providing for consistent input voltage to my amp.

This is a "must have" piece of gear. I was getting ~123v out of the wall, which was not ideal for my modern stuff, and even worse for my new-to-me pre-CBS Bassman. Glad I got this; now I run it every time I plug in.

I’m thrilled with it. I’ve resisted getting one because I didn’t want to carry another device around, but it really sweetens up the tone of my amplifiers. I wish I’d bought one years ago.

Excellent Cable. Long enough for any stage. Well made.

Knobs tend to work loose after agjustments.

An amazing product. Anyone who owns vintage audio gear should have one…or MORE!
