i think you'd need to get, or make a cable, if you want both right angles, that wouldn't be too tough. I just made some right angle speaker cables with 1/4 right angles. Its easy, you could probably get them at either radio shack, or go to a guitar store, but you could use a cat5 cable, and solder the tip/ground on the 1/4 in peices, and have that terminate into an 1/8 in stereo mini plug. i don't know how tough the mini plug would be to solder, but if all else fails get an old pair of headphones and hack the end off and use the existing wire in that. Good luck man, and welcome to ts.com.
