What We Think

Condition: Used, Excellent

Manufacturer's Description from Other

The basis for any signature world-class tone requires a consistent and dependable signal chain and for that, you need to start at the very beginning - powering your amplifier. The tone and performance of both vintage and modern tube amplifiers rely heavily on the input voltage powering them from the wall. Variations in input voltage can drastically affect your overall sound and performance and can shorten the life of the components. BrownBox allows you to discover and supply the optimal input voltage for your personal equipment and your personal sound no matter where you’re playing and what voltage you’re receiving from the wall. You’ll have a consistent basis for your signal chain every single time- guaranteed. You just need to find your magic number.
