Reddit mentions of BOSS TU-3 Chromatic Tuner Stompbox (TU3)

Here is what I use - The action was super high (still is a bit) but a couple of 1/4 turns on the truss rod solved that problem. Works fine. I also bought a Yamaha for the kid because this is heavy, it has better electronics but it also has jumbo frets which results in a lot of clanking noises if you're not gentle with it. It also didn't come with an amp or anything.

I also use this to split to the amp When playing bass I turn the in-game instrument down and listen to the amp. The game will give you credit for a lot of "clunkers" and sloppy play. Guitar seems to come out of the stereo speakers my PS4 is hooked up to fine, but it really helps to split to the amp with the bass. It also helps to preserve the real-tone game cable as I never really touch it, it stays plugged into the pedal.

Sure! I'll just use Amazon links just cause it's easier for me though you'll most likely be able to find better deals on Gear dedicated site.

The way I'm set up to use pedals with my amp and also send direct to Rocksmith; Guitar input to chromatic tuner, tuner output to pedals, pedal output to amp. Then, tuner bypass to real tone cable, RTC to USB. This way, I can have all my effects sent to the amp, and the bypass from the tuner is going straight to Rocksmith so the note detection is still working properly, but I have full control over my tone. Also, this allows me to mute the amp and only hear what's coming through Rocksmith by simply hitting my tuner pedal (I like the realism of hitting my own effects and such, so listening to the Rocksmith tone I can try to kind of match it). Very convenient and efficient for me personally.

Boss chromatic tuner that I use that ultimately makes this setup work. You could also use a signal splitter without a tuner, but I like the added utility.

Yeah, I was thinking to tell OP to buy one of these things, but when I read 'Floyd Rose', the only thing you could do was bring another guitar, or put those songs in a different place on the set list where you could interact with the audience while tuning silently with what I said to get.
