Pedal Tuners are a very convenient way of tuning your guitar, especially on stage. But you should always make sure you put your tuner pedal first in the chain, before other stompboxes. For easy and accurate tuning you need to give your tuner the cleanest possible signal - even the best tuner can struggle if you feed it distorted, delayed or chorussed signal!

To ensure that your tuner does not affect your guitar's tone, make sure your tuner pedal has a "true bypass" switch - this means that when it is not being used all of the tuner's electronic circuitry is switched out and the signal from your guitar is passed directly to the pedal tuner's output jack.
