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.

Fits well and comfortable!
Size: Large, Color: Eggshell White Black Mariner Stripe, Size: Large, Color: Eggshell White Black Mariner Stripe
This shirt fits my husband very well, it is true to size. It is soft and stretchy enough to be comfortable. I bought this as part of a costume but my husband wears it around the house now because it's so comfy.

You get what you pay for
Size: XX-Large, Color: Eggshell White Black Mariner Stripe
Like most of the other reviews here, the shirt runs too small and too short. Material was also incredibly uncomfortable. It also wasn't the color I was hoping it would be, but that's on me for not reading the fine print (eggshell white was very much not white) If you're looking at this for a certain costume/cosplay idea, it's probably not what you're looking for.

Great tee
Size: X-Large, Color: Medium Grey Heather
It’s a nice cotton material…not thin, just perfect. After washing, it also kept its shape.
