Does anybody sell these in stores or am I going to have to order online?
Where could I physically buy a Trrs 4 pole 3.5mm jack?
What for? Usb cable will have 4 wires plus the shielding, red green white black + shielding. The red and black are normally thicker then the green and white wires. 2 usb connections would need at least 7 pins if you were trying to make some kind of a usb extension cable. I guess if you have 6 pins plus the outer ground you could get away with fitting 2 usb connections. I've seen xlr used for case mods where they didn't want to just have normal usb ports but it was more of an art piece.
So your a local? jk is a great shop, i have been going there 15 years. Marvac electronic's is also a good store but i haven't been there in ages.
Oh and if you want to make it on this forum and others don't start so many threads, be patient someone will reply and you might even get a nice thread started.
