Demo units have been used in the field and at trade shows. They typically have minor cosmetic defects only,  such as dents, scratches, painting errors, and misprints which do not affect the sound quality and usability of the product.  Demo purchases come with a 1-year limited warranty. 
 
From the makers of the acclaimed Fatboy Tube DI comes the Teegarden Audio 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 Magic DI was fine-tuned to excel on acoustic guitar & stringed instrument pickups but sounds equally stellar on keyboards and bass guitar. The flexible Combo XLR/1/4" input jack, combined with the Pad and the Active Buffered Thru can also be used to reduce line level signals to instrument level and function as a ReAmp device.  Pure. Simple. Magic!
