Well, I use a USB to midi cord which plugs into the midi IN jack (that piece has both IN and OUT) and then the GB link cable to my GB. I have a custom ROM on my GB that translates the data from the pedal into sound. My gameboy has what is called the "prosound mod" which routes the pre-amp audio to a custom fitted headphone jack, which removes static introduced by the internal amp. It cannot power a pair of headphones, but is not intended for this since I kept the stock headphone jack. It is used strictly as a line-out jack. From there I plug it into my line-in on my desktop and record.
My gf has a cheap pedal that she got ages ago called "French Toast." I want to see what it can do when introduced to this little setup.![]()
