Brand New. Hand wired in Music City, USA. 

From the manufacturer:

TAKE CONTROL OF YOUR SIGNAL CHAIN AND BEGIN BUILDING A SIGNATURE WORLD-CLASS TONE ALL YOUR OWN

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.

The best lower unit gear oil I have used
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
I have been boating my whole life, this is by far the best gear oil. I use this in my Johnson 115 even though this is technically made by Mercury. I seem to get less if any water intrusion into my gearcase with this oil. If there is any, the oil emulsifies the water and continues to protect the gears. I have had better luck with this than Pennzoil marine or others. Highly recommend. It is a blue color and easy to drain and fill.
