This Hosa Stereo 1/4" Angled Male to 2 Mono 1/4" Angled Male Y-Cable is a "send/return" cable (also known as an insert cable), conventionally wired: Tip = Send, Ring = Return. It can also be used as a "Y" cable to split a stereo signal into Left and Right signals. In this case, Ring = Right and Tip = Left.
