There are many fine sounding vacuum tube direct boxes on the market. However, in Teegarden's listening tests, none of them compare to the air and depth delivered by the Teegarden Audio Fatboy Tube DI. 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 modern recording equipment. A lot of this was due to a departure from proven classic designs, the use of substandard parts and a slip in quality of manufacturing. The Fatboy puts an end to these practices that were based largely on cutting costs and not improving sound quality.

Teegarden's team of electronic engineers and professional recording engineers are pleased to give you the definitive standard in instrument level direct injection recording – THE FATBOY TUBE DI
