B-Stock units typically have cosmetic defects only,  such as dents, scratches, painting errors, and misprints. They do not affect the sound quality and usability of the product. B-stock purchases come with a full Teegarden Audio 2-year limited warranty. 
 
From the makers of the acclaimed Fatboy Tube DI comes the Teegarden Audio Stereo Magic DI, a transformerless, balanced, active, direct injection device that offers maximum headroom, low distortion, and pristine sound quality. It can accept input levels from passive guitar pickups or piezo transducers up to line level console or preamp levels (-40dBu to 0dBu). ​The Stereo Magic DI was fine-tuned to excel on acoustic guitar & stringed instruments but sounds equally stellar on keyboards and bass guitar. Pure. Simple. Magic!
