Have you ever said, "My guitar amp sounds different today!" You're not going crazy, the voltage from your wall is changing! Protect and hear your guitar amp the way it's supposed to be heard. The AmpRX Brown Box is a must have tool for guitar players who play through tube amplifiers. The Brown Box is a voltage attenuation device, it takes the voltage coming out of your wall and lets you see exactly what it is and allows you to adjust the voltage down to a proper voltage. Many outlets in the USA put out more than 120 volts which can damage, or change the sound/feel of your amp. Further more vintage guitar amps were really designed to run at 110 volts, the Brown Box let's you operate these safely.

Dropping the voltage for modern guitar amps change the feel and sound in subtle ways that let you make sure your amp is feeling and sounding right. Use it at home, take it to gigs, once you get used to having a Brown Box you won't want to play without it.

Functional jewelry box with nice see through top.
Color: White, Size: 3 Drawer, Color: White, Size: 3 Drawer
Lovely jewelry box at the right price. I got this to match the corresponding rotating jewelry box here on Amazon and they look really nice next to each other. I didn't get to fill this up yet but I will update when I do if I need to add anything. The drawers are roomy and will hold a lot. I like the design of the see through top so I can see what pieces I have and use them more hopefully. It's not glass it's plastic and it's not the highest quality jewelry box but it does the job. I love it.
