Got it, so the main difference between what he sent, this, and the ABY I posted at the start is just that since I don't need the "A/B" and only the Y I can achieve the Y from a regular tuner pedal and also get the tuner function, right?

Never used pedals actually, so excuse me if my question is pretty dumb, but what's the difference between what you sent and this one from the sidebar?

And also, can I achieve the "Y" from an effect pedal or different sort of pedals? And again, excuse me for the question if it's obvious but why would you need a tuner pedal if there's already a built-it tuner in Rocksmith?
