Rack signal chain question - splitting signal to tuner

[luther]

ok - I've got a signal coming from my amp effects loop into an effects unit in the rack. *Signal continues to processor number two, *and then back to the return. *Everything is mono.

I have a Korg DT-1 in my rack that I would like to be 100% active when I'm playing, *but I don't want the real signal to go through the tuner (it is noisy).

So I'm thinking set up a "Y" connection and send one signal on, *and the other into the tuner. *Will I be reducing my signal if I do this? *What device is highest quality and best buy for this application? *If this is the best way to do this where do you recommend the "Y" take place?
