Teegarden Audio Fatboy Tube DI Stereo Rack

Stereo rack mount vacuum tube DI with nickel transformer
MFR# Fatboy Tube DI Stereo Rack

Product Description

There are many fine sounding vacuum tube direct boxes on the market. However, in listening tests, none of them compare to the air and depth delivered by the Teegarden Audio Fatboy Tube DI Stereo Rack. Simplicity and perfection meet.

As veteran recording and design engineers, Teegarden knew what they wanted to hear when they set out to bring the Fatboy Tube DI to the audio recording community. They, like many of you, have been missing the richness and definition of sound in most modern recording equipment. The Fatboy Tube DI has become the vaccum tube direct injection box by which all others are measured.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
