Say: "My D-I"

I only have one DI box, and needed more, so I decided to build my own. It has a 1/4in. input, balanced XLR output, and switches for ground lift, -30dB pad and phase flip.

The heavy duty metal box was $2 at a thrift store. The rest of the parts were pulled from other (free) items I found (e.g. The transformer is pulled from a broken sound mixing console I got free on Craigslist).
