So I was looking through the rocksmith tag on github and I found this https://github.com/fluffyanvil/Rocksmith-Diy-Realtone-Cable

 

I know it's probably pointless and more expensive than just buying one but It looked interesting.

Seems more hassle than coughing up the money since you need a low end sound card and an audrino.

 

Good luck with it

RS sounds better if you use an amp anyways. Most sound cards have better hardware than the RTC. So I use nocable.

 

In direct comparison to my RS2014 RTC, this setup has much better sustain and does not have that awful decay noise that the RTC does.

definitely the part of the game that needs updating the most... I play thru my amp, but the rocksmith cables just fiz out over time....
