Jacks wiring

[Jamiroking]

I'm in the middle of wiring my krankosaurus and am just getting into the jacks and switches. I'm alittle confused why the diagrams call for TRS jacks for the inputs though. Not only is nothing hooked up to the sleeve but even if there was, since patch cables are TS, aren't both ring and sleeve going to the same place? I already have my parts but for next time, couldnt the same result be achieved with a TS jack and and the 9v- hooved up to the sleeve? Forgive me if there's an obvious answer here.
Thanks

Hi,

the Sleeve of the input jack doesn´t need any connection to ground through a wire since it is already physically grounded to the enclosure. It´s just an extra feature to save battery-life. As soon as you pull out the input cable , the battery will be disconnected from the circuit. When you connect your guitar to the input, it will short the Ring to Sleeve, and thus supply the circuit with power from the battery.


You could just use a mono jack if you´re not planning on using batteries.

AHH!! The battery life! I forgot all about that.
Thanks a lot!
