Tag a hater This question has sparked debate for centuries! Well, maybe not that long, but people are certainly passionate about it. Variacs are definitely cheaper, but if you want to keep your rig as safe as possible, invest in long lasting road-rugged gear, and get rock solid customer service to boot, we think you might want to consider a BrownBox. If you love AmpRx gear and care to opine, leave a comment and let us know why! We WANT the debate here, so we’re serious - tag a hater! Let’s hear their side, and change some minds! #brownbox #voltagematters #vintageguitars #musicgear #amps

Learn how to use the BrownBox! Here’s the quick rundown: The BrownBox is an adjustable AC power supply for your amp or tube gear that helps you run your equipment at the optimal voltage. Plug the BrownBox into the wall, adjust the voltage and then plug your gear into the BrownBox. When a tube amplifier is supplied with the proper line voltage, it will sound and respond as originally intended, revealing the circuit’s true harmonic content, and preventing unnecessary, expensive, and frustrating repairs. BrownBox users testify time and again as to how their amp’s tone, touch and feel have finally come together, providing them with improved harmonics and dynamic amp performance- allowing them to capture the elusive tone they’ve always wanted, every time, everywhere. #BrownBox #VoltageMatters #howtovideo #guitars #musicgear

Hot Take: P Bass is better than Jazz Bass. Also, Round-Wounds over Flat-Wounds @amp.rx @clarksingleton_ #hottakes #guitar #NAMM2026 #Bass #pbass #amprx
