My new band is tuning down to drop c. And i hate floppy strings. SO im using. 11 14 18 38 48 58. Theyre kinda tight. I just want to make sure their not gonna fuck up anything. Its an ESP V fender scale.

Adjust the truss rod accordingly to deal with the higher tension. It will almost certainly affect your intonation(not a whole lot, but you want this to be perfect for recording) and might cause some neck warping.

That sounds reasonable to me. Does your ESP have a Floyd Rose bridge?

Edit: Also yeah like somefella mentioned it is truss rod, not thrust rod. Great typo though.

String through
My buddy knows how to do the thrust rod stuff. Ill ask him to take a look

I would advise going with something a lot lighter than 38 and 48 on the 4th/5th, I used 11-15-22-30-42-58 from drop C and while the third was a bit tight (which I wanted), those were a good match. Those two are way too heavy while the rest are just about right. ESP string-thru guitars come set up with 10-46 so if you replace those two with something more like what I suggested you may not need to adjust the truss rod since it's roughly the same amount of tension. Remember to intonate it!
