Mono Versus Stereo
What the rings do
TS carries one signal. TRS carries two, or one balanced signal.
Why guitars use TS
The pickup signal is unbalanced. A TRS plug works mechanically but connects nothing to the ring.
When TRS is correct
Balanced line gear, stereo effects, insert loops.
Checking before buying
Match the plug to the jack’s specification, not the other way round.
