I personally like grover tuners betre
There are many brands of guitar tuners to chose from. One of the best and most famous brands of guitar tuners comes from Fender. Another great brand of guitar tuner is made by Les Paul.
As in when you buy it? Usually no, but i suppose on who or where you are buying it from. Lots of times, when you buy one you can ask where they keep the electronic tuners to help you tune the guitar, or maybe you could ask someone to do it for you.
tightening the tuners on the guitar change the pitch strings are just like shoes they all do the same thing but some are better for some and some are worse for others.
Depends its might be a bit of confusion there are machine heads (tuners) and a guitar neck.
Online guitar tuners work by using the microphone facility on a web cam to record the guitar notes. It then uses both the proper notes and usually a visual guide to help the user tune the guitar to the proper sound, and graphical pattern.
Yes, yes you can. If you couldn't tune it like a regular guitar they probably wouldn't of put tuner pegs on the tuners.
It is like asking why do drum needs drum sticks
Cut them on the tuners after they are strung.
some no name guitars have surprised me , as long as you get a good sound that is what matters. look for good tuners , grover , schaller , sperzel ...ect if the guitar can be googled check to see what kind of woods it has worry about pickups it has last any questions feel free to ask
you can tighten or loosen your strings, causing the string make higher or lower sound. (Check guitar tuning)
